I stopped by Jo-Ann Fabrics to look through their collection of sewing thread. They had some nice colors in the Gütermann Dekor embroidery thread, so I bought one to try it out for tatting. It's 100% viscose and color #9945. I used it to make a heart:
This is the first time I've tried tatting with something other than cotton. I was surprised because it was easier to work with than I thought. It's VERY tiny though. Smaller than size 100 tatting thread, and nearly impossible to see the stitches. The picots don't keep their shape very well (the thread unravels), but the heart pattern doesn't have any decorative picots so it worked out okay.
Here's a photo comparing the sizes. Size 40 Lizbeth on the left, Güterman Dekor in the middle, and size 20 Lizbeth on the right:
Overall a fun experiment, but I'm not sure how often I will make something so small. It's difficult on the hands because the stitches need to be snugged very tightly. The rings were hard to close at times and I couldn't really see what I was doing when I sewed in the ends. I do like how tiny it is though:
