Thread, thread

[Barb T]

I did a little sleuthing on the Internet, and I think I've found some answers to the cotton and silk thread question. Cotton thread doesn't have much "give", and it's OK on cotton and linen, which don't stretch much. I also found a lot on the problems of using poly thread on cotton fabric for piecing quilts, because the poly thread apparently cuts the cotton fibers over time (??that's what I read). On the other hand, polyester and poly-mix fabrics have a little stretch. Because cotton thread doesn't have much stretch to accommodate the slight stretch in the fabric, cotton thread is more prone to breaking over time if you use it, instead of polyester thread, on poly fabric. Wool is a little stretchy, too, so I'm guessing that polyester might be a better choice than cotton for the same "give" factor.

I did find a lot on the Internet about the deterioration of silk fabric and thread over time. So, I don't think you want to put a lot of work into a kilt and have the silk thread rot on you.

So, I think 100% polyester for wool or poly-wool mix is the best.
