I've used fabric.com a bunch of times and could recommend them. Sorry I don't know about Design Diva.

I've ordered from the Fashion Fabric Club and can recommend them.

I like Design Diva Fabrics. However, on my monitor, colors appear brighter than they really are. I notice this frequently with DDF fabrics. So, I encourage people to order samples. Also, shipping costs are significant. I have ordered a lot of fabric from this firm, including many kinds of linen, several cotton prints, and some silk. They are lovely. I even made a little cat bed pillow with a Scalamandre linen from DDF. (The cat still prefers lying on my copier, but that's her problem.)

Another recommendation for Design Diva :-) Their shipping is always very prompt and I have been very satisfied with them so far.

I have also had good luck with fabric.com and fabricmartfabrics.com.

Hi, all, I just opened my own online shop. Would love for you to visit and compare my prices and shipping rates. I'm expanding my line over the next few weeks. Thanks!
