I may not do many of these; they’re not nearly as much fun as the triangles or longer diamonds. The single-bead Comanche stitch that makes up all but the center row is very tight and hard to work. It’s easy to get the needle in slightly the wrong place and have to pull out a stitch.
That said, the tactile effect between my fingers is interesting, because the Delica beads snap together like little glass bricks. It’s almost like fingering a waterglass turned flexible.
