I have a lot of RA (Robinson Anton) rayon embroidery thread. It is very pretty. I used to machine embroidery. I have also used to do applique on wall hangings. It is not supposed to hold up as well as polyester threads or cotton threads. I recently made a small wall hanging of a skunk! It was fun, I used a gold rayon thread and an eyelet stitch to make the little eyes. They sparkled! For embroidery, I think the Rayon thread adds a depth of color that the poly threads just don't do. Depending on the stitch position, the color changes slightly making it very pretty. I think it would be fun to do thread painting with it.

If you don't already... maybe it's time to try thread painting with your sewing machine. There are tons of free videos available online to get you started.

I do machine embroidery and the rayon thread needs "Sewer's Aid" to keep from shredding or breaking in the needle. The embroidery machine sews a lot faster stitches per inch which is part of it. But I would not use it to quilt.

Finding out that Rayon thread is not colorfast and can bleed if washed convinced me that I'd never use it. I always wash my work. I also believe these threads must be very old too. They are quite fragile and break easily when pulled on... but they are so BEAUTIFUL!

My solution was to buy a two gallon glass container to display them as a decoration. Would you believe that container is not big enough to hold all of them? I'm not sure what I'll do with the rest, but the drawers should come in handy for something... storing patterns maybe?

I hadn't had much of problem with RA rayon Threads breaking but you should use the right needle with them. I can't remember the size I used but I think it was a bit bigger than my usual needle.
