So all this Gutermann I have been buying at 50% off I need to stop.. lol I like having a wall full of all colors so have been buying it whenever Joann had it on sale. I did buy Bottom Line when I re-upped on The Quilt Show they had a coupon for a free spool.. I got Black and White and I love it . it seems to last forever. I am using up all my Coats and Clark because now that I have use the Gutermann , the C and C justs seems so linty . I have to stop and clean out my machine a lot. I am going to check out the Aurafil. The only thing is if I run out and am in the middle of a project I have to wait for the mail. :-)
