This is the leaf pattern in the book. So first you knit to the proper length, then T-pin it out and starch and iron.
Next, launder your fabric, and if using purchased cases, cut about an inch above the hem and sew hems on each side using a basic stitch. Then hand sew your pieces together. The lace will shrink a bit when laundered, however it will return to it's shape if ironed flat. Viola!
