I found these diamond stitch patterns when looking through a book of old German charted designs that date back to the early 1900s. I updated the designs to use both left- and right-leaning decreases, and used a modern method of denoting the stitches in the charts. Since the design was inspired by German knitting techniques I named the pattern Diamanten, which is German for Diamonds.
Both scarf and shawl are knit from the cast on edge straight through to the bind off edge. Edge points are made by a series of increases and decreases worked into the lace.
