This is a basic chain stich done with Trellis Yarn. Seven strands tied together and a loose knot at the end. There is no clasp on this as the person that is going to wear it just has to adjust the length and tie a knot.  So simple to make and with this design you can make so many variations using different types of yarn. Plymouth Electra works great and so does dazzle lash yarn.  I have made a ton of these and some of the ones that are more geared to cooler weather I have added beads and flowers to them.

The expense is so minimal and they are very attractive on. My mother in law taught me how to Crochet a few weeks ago and I have been addicted to making them. Would be good for a craft fair as a source for inexpensive items to sell. With the economy as it is today we all have to look at alternative ways to sell our craft.
