These legwarmers came about because “Necessity is the Mother of Invention!” And, because I wanted legwarmers I could remove without taking off my boots. These lace and cable leggings are knit flat, and then fasten up the side of the leg with either buttons or a zipper -- directions for both are included!

For questions and support, please e-mail me at

Pattern Notes:

The legwarmers are knit flat (on straight or circular needles) and are fastened around the leg by either buttons or a zipper. Optional eyelets at the top allow for a cord or a ribbon to be threaded through and tied.

This pattern has written instructions, and the stitch pattern is both written and charted. This pattern also has an accessible large print option that is compatible with screen-reading software. This option includes only the written instruction.
