I think Connecting Threads fabric is good quality, but the designs have never appealed to me.
I buy most of my fabric on-line, and usually on sale.
My current favorites:
http://www.hawthornethreads.com - very good sale selection
http://www.maryjos.com - incredible shop, I envy anyone who can get there in person
http://www.favoritefabric.com - she's a Board member: good selection, service and prices *
http://www.hancocks-paducah.com - expensive, but have wonderful selection in their sale sections
http://www.fabric.com - the best prices for Kaufman Kona solids + spend $35 or more and shipping is free
http:www.4my3boyz.com - the best selection of novelty fabrics I've found; always has many FQs for $1
* if you order, remember to sign up for their frequent buyer program
