Having been led astray, to JoAnn's craft and fabric store website, I found many things which might prove useful to the casual fly tyer. I started using DMC floss when I was a teenager. DMC cotton floss has little life expectancy when exposed to water &/or fish teeth, which is a drawback for a fly-tying material. DMC wool floss is an altogether better proposition. Sometimes I use DMC (or other) silk, embroidery floss. Today I found something new to me. I discovered DMC in linen. Linen is a most interesting material and it can have very different characteristics depending on how the thread and cloth are made. I find myself wondering if any of you have tried this material and if so, what you think of it. I am interested in the durability and colorfastness, among other things.
