Explore Fascinating Knitted Cables with the DNA Pullover

The DNA Pullover, from Interweave Knits Winter 2019, is a striking Aran-sweater paying tribute to molecular biology, inventive cables, and sophisticated menswear.

“[The DNA Pullover is] inspired by the work of Rosalind Franklin and so many others to decipher the elusive molecule of inheritance,” says designer, Andrea Cull.

Every cable on this pullover has meaning and is utilized perfectly. The DNA strand is textured with seed stitch and twisted rib, giving the cable a three-dimensional appearance. And the simple and central plaited cables symbolize RNA and proteins.

Combining science and knitting comes naturally to Andrea. After the school bell rings, this AP Biology teacher frequently trades pencils for knitting needles. And between knitting for various Interweave knitting titles, she combines her passions for knitwear and the inner workings of cells by making “bio” knits; knitted objects that mimic or represent biology themes. “Bio” knits include things like knitted hearts, frog dissections, and models from anatomy and astronomy!
