The Handknitter’s Double-Knit Buttonband

When I knitted my first cardigan, I followed the directions for the buttonband carefully, experimenting with different needle sizes and types of buttonholes. But despite my best efforts, I ended up with a droopy band and sagging buttonholes. I was so dismayed that I never wore the cardigan. So I started searching around for a more stable type of buttonband. Nothing I found was quite what I was looking for, so I made a list of the attributes I thought the buttonband should have and set out to make one that would meet the following criteria:

• It could be added after the sweater was blocked and assembled.
• It would be sturdy and stable, even in yarns made of drapey or inelastic fibers.
• It would avoid the uncertainty of achieving a particular gauge.
• It would have self-finishing buttonholes.
• It would require only basic knitting skills and no special tools.

The buttonband “recipe” you find here is the result of many, many experiments. I wanted to make a buttonband and buttonholes that would last as long as the sweater. I haven’t had quite enough time to test that theory, but I can say that the bands I have made so far have worn steadfastly and beautifully. I take pleasure in them every time I put on the garments they adorn.

There are as many types of knitters as there are types of yarn, each with their own preferences and skill set. Although techniques work differently in every pair of hands, I tried to develop a pattern that would be accessible to most knitters. While creating this recipe, I felt the intrepid spirit of Elizabeth Zimmermann at my side. Her philosophy made me feel that I had both the right and the ability to “unvent” something. I hope you will feel the same. I encourage you to use this recipe as a jumping-off point for your own “unventions.”

We’ll begin with an overview of how the buttonband is worked, followed by specific instructions for each part. I’ve provided the directions with as much detail as possible because this process might be new to you. After you’ve done it once, you will see that you don’t have to slavishly follow directions—the process is fairly straightforward. If you prefer, try adding a buttonband to one of your swatches to get the hang of it before using it on a full garment.

Overview

The double-knit buttonband is worked on a set of double-pointed needles several sizes smaller than the gauge needle of the sweater. Stitches are worked in double knitting to produce a tight fabric that has a stockinette face on both the right and wrong sides. The thickness of the fabric helps support the weight of the buttons and prevents distortion. The buttonholes worked into the double knitting are sturdy and do not stretch out with use.

You work the buttonband after the sweater is blocked and assembled so that you can use the finished length of the fronts to determine the length of the bands. The buttonband is worked vertically and sewn to the cardigan fronts. The recipe is suitable for crew necks, funnel necks, and (with slight adjustments) V-necks.

How to Make and Attach the Buttonband

• Once the sweater has been blocked and assembled, measure and record the length of the cardigan fronts. You work the buttonband first so that you can accurately calculate the buttonhole placement. After casting on, work the band in double knitting until it is roughly 1″ (2.5 cm) longer than the recorded length. Keep stitches live on a stitch holder or spare double-pointed needle at the end of the band in case you need to adjust the length (Figures 1 and 2). I find it easiest to get a good fit if I work the band slightly longer than necessary and ravel any additional length after I’ve sewn most of the band to the front.

• Wet-block the buttonband by immersing it in water with a no-rinse wool wash for at least 15 minutes. Squeeze out excess water, then wrap the band in a towel and press to remove as much water as possible. Pin the band, slightly stretched, to a blocking board or towel. When it’s completely dry, unpin the band and let it relax for several hours to its final dimensions. Compare the relaxed band measurement to the cardigan front measurement. If the band is too short, add length before proceeding. Double knitting and wet-blocking result in a stable fabric that has already experienced any likely growth in length, so the band is at its finished length before it is attached to the sweater.

• Pin the band to the appropriate side of the cardigan and sew it to the garment selvedge from the bottom edge to the top using mattress stitch (Figures 3 and 4). When you are nearly finished sewing, you will be able to see if there is any excess length in the band. If there is, the extra length can be raveled and bound off to match the length of the sweater front (Figures 5 and 6). The mattress-stitch seam will prevent both the band and the cardigan front from stretching lengthwise over time.

• After the band is attached, you can take the gauge of the double knitting and determine how many rows there are per inch of fabric. Then you can determine the buttonhole placement either visually or mathematically. (Each buttonhole is worked within a single row.) For the visual approach, simply lay the buttons out on the band to see where you want them, mark the locations with coilless safety pins, and count the number of rows between each button. For the mathematical approach, place the top and bottom buttons where you would like them, then either measure the distance between them or count the number of rows. If you are measuring length, divide the measurement by one less than the number of buttons you would like to use, then multiply this number by the double-knitting row gauge to determine the number of rows between each buttonhole. If you are counting rows, count the total number of rows between the top and bottom button and divide by one less than the number of buttons you would like to use. Doing so will give you the number of rows between each pair of button holes. (See the Keeping Track of Rows in Double Knitting section below for more information.)

• Cast on for the buttonhole band, working the self-finishing double-knit buttonholes (see instructions below) at the intervals you determined. Wetblock this band as for the buttonband, then sew it to the other side of the cardigan front with mattress stitch.

Double-Knit Buttonband Structure

Note: The buttonband will be on the left front for women’s garments and on the right front for men’s garments.

The band you are creating has a total of 14 stitches: six pairs of double-knitting stitches and 2 selvedge stitches. The single selvedge stitches give the band structure at the edges and make it easier to sew. The double-knitting stitches provide a fabric with two faces; you are only working half of the double-knitting stitches on each row. Therefore, it takes two passes of the stitches to add a single row of length. Working the band over 14 stitches generally results in a width of 1–1½” (2.5–3.8 cm). If you wish to increase the width of the band, increase the stitch count in increments of 4 stitches to add two additional pairs of double-knitting stitches at a time; doing so will keep the buttonhole centered.

The structure of the band looks like this:

p [k:sl | k:sl | k:sl | k:sl | k:sl | k:sl] k

Work the band using two double-pointed needles four or five sizes smaller than your gauge needle. To prevent the bottom edge from flaring, you may want to cast on using a needle one size smaller than your band needle. In general, for yarns ranging from worsted weight to sportweight, I use a U.S. 2 (2.75 mm) needle for the double knitting. For fingering or laceweight yarn, I use between a U.S. 1. (2.5 mm) and a U.S. 0 (2 mm) needle. Needle size will vary based on the texture and makeup of the yarn, but exact gauge is not important; you just want to achieve a dense fabric that you like.

I’ve knitted this band in a variety of yarn weights ranging from lace to worsted. Because I prefer a narrow band, I usually use a 14-stitch band regardless of the weight of the yarn. However, feel free to adjust the width as desired. If you are substituting this band in a pattern that calls for another type of buttonband, make a small sample so you can tell how many stitches you will need to achieve the width of the band called for in the pattern.

A note for V-neck cardigans: work the two bands to the length of the center back neck, sew them down most of the way, and join the two bands together before sewing the last inch or so to the center back neck. You can join the two bands by grafting, by using a three–needle bind-off, or by binding each band off separately and sewing them together with mattress stitch.

Double-Knit Buttonband Instructions

Using the long-tail method, CO 14 sts.

Row 1 K1, [sl 1 pwise wyf, k1] 6 times, p1.
Rep Row 1 for patt.

The right and wrong sides of the band will be identical; only the cast-on row will look different, so choose your right and wrong side based on which edge you prefer to have visible. Work the band as described above. Bind-off row K1, [k2tog, pass 2nd st over first] 6 times, k1, pass 2nd st over first.

Double-Knit Buttonhole Instructions

The 14-stitch band works well with a 3-stitch buttonhole. If you have made a wider band and would like a wider buttonhole, work to the desired point for the buttonhole, follow Steps 1 and 2, then repeat Step 3 over pairs of stitches as needed. In Step 6, make sure to cast on enough stitches to compensate for those removed in Step 3.

The 3-stitch buttonhole is worked all in one row. Work to the rightside row where the buttonhole will be placed, then proceed as follows:

Step 1 (RS) K1, [sl 1 pwise wyf, k1] 2 times, RLI into the bump of the next purl st.
Step 2 K2tog, pass inc’d st over—1 st BO, 7 sts rem on left needle.
Step 3 K2tog, pass 2nd st on right needle over—1 st BO; 5 sts rem on left needle.
Step 4 Sl 1 pwise wyb, pass 2nd st on right needle over first st—1 st BO.
Step 5 Transfer first st on right needle to left needle.
Step 6 Using the cable method, CO 5 sts onto left needle—15 sts total (on both needles).
Step 7 Transfer first st on right needle to left needle, pass last cable CO st over it, then return st to right needle—1 st BO; 14 sts rem.
Step 8 Tighten up working yarn, then [sl 1 pwise wyf, k1] 2 times over cable CO sts, sl 1 pwise wyf—4 sts rem on left needle.
Step 9 K1, sl 1 pwise wyf, k1, p1—buttonhole row complete.
Turn work and resume 1-row pattern over 14 stitches.

Keeping Track of Rows in Double Knitting

Remember that as you are working double knitting, every row you count on the fabric consists of two passes of the buttonband pattern. It is helpful to put a pin around a stitch on the buttonhole row to facilitate counting rows for future buttonhole placement. Because it takes two passes of the stitches to work one row of double knitting, it is simpler to consider the buttonhole row as Row 1 of an even-numbered group of rows; for example, a 24–row section consists of 48 double-knitting rows. Therefore, after the buttonhole row, you will work the one-row pattern 47 more times. Doing so completes one 24–row section. You will begin the next 24–row section with a buttonhole row and so on.

I hope you’ve found this tutorial informative and that you attempt this “unvention” on your next cardigan or accessory requiring a buttonband. For instant gratification, try this recipe on the Doresu Cardigan from knit.wear Fall/Winter 2016. The buttonband on the long cardigan adds both structure and a beautiful design element to the garment.

    I sewed before I began knitting, in sewing you do the buttonhole first and then you can position the buttons after you have everything all finished. I think it would be easier here also to make the buttonhole and then be able to place the buttons where the buttonhole is.
