For those who don't know yet, Caron has completely redone their website, and I am so thrilled.
Caron is one of the best-known specialty threads manufacturers in the US, and I've used all of their major product lines. Watercolours, Waterlilies, Wildflowers, and Impressions (a wool/silk blend thread). They've got many impressive colorways which you can now easily see on their site here, and while you're there, check out their lesser-known threads. If you like variegated thread, you'll love Caron. If you like free patterns, well you'll just have to love them twice then. I'm getting ready to do their Byzantine Xmas ornament (needlepoint), and there will be pictures.
