I see that this is going to be one of my favorite places on this site. I get probably 50% of my material from the internet. You people who live around JoAnn's and large cities where there are alot of options are really lucky. Our closest JoAnn's is about 75 miles from here.
I go to this great little eBay store to get so much of my material. It's like "On Sale" everyday there! Right now they have 949 fabrics listed! so they do have a good selection too! They sell Red Rooster fabrics for $2.99 a yard! There are other materials too, mostly $3.49 or so a yard. They do have some others that are more expensive but hundreds that are really reasonably priced.
And their shipping is great! 8 yds is $4.95 and 28 yards is $10.70. That's not bad at all. I love the store. It's in Mass. I think. Here's a link to it. You really ought to check it out. Material prices these days are horrible! I support the people who aren't trying to get rich off every piece sold. :)
