As yet, I don't have my FSL angel put together for a pic, but am working on it. In the meantime, I tried a couple of ornaments and decided to try serger thread thinking it would be thinner and make less bulk on the ornaments. It worked like a dream. So, back to another angel. Since the serger thread worked so well with the ornaments I thought I'd give it a try. The angel body has 37,000 stitches, lots of bulk, and doesn't seem to like serger thread. About 45" into the stitching I got a major birds nest and had to cut it out of the machine. So back to the other thread. I just read in the new CME magazine that generally designs are digitized for 40 wt thread. Good to know.
