Had trouble sleeping at 11 PM or so tonight (it's after 2:30 AM), so I got up and pieced some more HST crumb blocks a la Scraps a Plenty.
After taking this picture I pieced 8 more. Each little block is 4-1/2" square unfinished. This represents a chunk 16" tall by 36" wide. Many more to go, but I have a big stack of pieces pressed and trimmed for adding on more units. This is fun, but takes a long time. It's kind of mindless sewing, so it is fun and relaxing. Looking forward to seeing the finished product, as usual (way early).
