The outer yellow petals are blanket-stitched in Glide by Fil-Tec Threads. The inner red petals are stitched in an Aurifil Polyester 40 weight thread. I have searched for more of this, but they no longer make it. The very pale yellow fabric is stitched in Mettler 60/2 cotton thread. Since this Mettler thread is cotton it has no sheen and really blends into the background. Using this thread is a nice way to make part of the block soft and flat in sheen. The dotted red and yellow fabric is blanket-stitched in Deco-Bob by Wonderfil Threads, a nice polyester thread. It doesn't have quite the same amount of shine as the Glide, but it's close. The large dot is stitched in Sulky Rayon 40 weight thread. The little dot is stitched in Isacord machine embroidery thread.
Some things I have learned so far:
- Cotton thread really has no sheen and is excellent if there is a piece you don't want to stand out.
- Bottom Line Thread has a little sheen, but because it's 60 weight leaves a very thin line.
- Glide, Isacord, Deco-Bob, and Sulky 40 weight threads all sew beautifully and have similar amounts of sheen.
- Fufu thread is really shiny and way easier to sew with than metallic thread.
