It's been only a few weeks since I started Marion Foal's Diamond Jacket (from Marion's Knitting Collection 1) and I already wonder if I'll ever get it done. At a gauge of 8.5 stitches/inch on size U.S. 1 (2.25 mm) needles, there are a lot of stitches and a lot of rows to knit. So far, I'm only about 7" into the first sleeve. But I do love the soft lightweight fabric produced by the small needles. The marker is to help identify right-side rows (the stitch pattern is reversible).
