I immediately thought of reading an article about fabric-shot cotton is used by K Fassett a lot and it is very thin fabric. I think he is a awesome artist! If it's the color you need you can use interfacing etc. guess what I mean is it's not so much about the thick or thin of fabric so much as from the artist eye use what you love be it color,txture,movement etc. I do think the well known designer fabric is more expensive but Oh Well you're payng for their creativity!!Others on this Board can explain it better than I can! I just buy what I love no matter what the weight!
