Love the lace edging, and the knot design throughout.

The free pattern goes up to size 5X, and is called "Satin Lace Edge Cardigan", from the Bernat Yarn website. I used Bernat Satin yarn in a bright Lavender color.
If you know of a knitting pattern (free or not) for plus-sizes, please post a comment.
