I got to be a tester for another one of Caroline’s patterns: the Waterfall Tank. (releasing Monday!) This was my first time using rayon challis and I think I might be hooked. It has such a great drape to it- perfect for garments. It is a bit fiddly to sew with so you have to be careful when you cut it out but other than that, its not too bad. I got this particular rayon challis at Wanderlust Fabrics (out of stock right now 😦 ). I just recently discovered them and highly recommend them as a good resource for knits and rayon fabrics. The quality is great, and they will even send you samples upon request so you can see the fabrics before you buy. I got two other knit fabrics with my order and am looking forward to putting them to good use in the near future.
