you will get a vast difference in opinions on this subject I am sure...I am only reading the first page here..
anyway, I have worked in textiles for more than 25 years and was a buyer for a large chain store...the quality of the fabric at CT is mediocre....some can be decent, but the most of it is lesser quality. it is comparable to hobby lobby, joann and hancocks...not quite walmart, but close! It is definately NOT quilt shop quality...however LQS fabrics are changing as well due the lower thread count greige goods being used now to conserve cotton...at best it is a crap shoot anywhere these days. BUT let me say that with black you need the BEST quality you can find, it does not wear/hold color as well if you buy lesser quality!
