I don’t know about you, but sometimes finding the right size AIDA cloth is tough (especially for larger projects), but I found this seller on Etsy who has reasonably priced AIDA cloth cut in large sizes. For example, a piece that’s 20.5″x18″ is $3.50 plus $2 in shipping — dude, I paid $12.99 for my piece of AIDA cloth for the Dark World map.
Linkage to cheap AIDA cloth — whee!
The only word of caution is that it is on black cloth. So if you hate to stitch on dark fabric, this isn’t the deal for you. But, if you can handle the black, you should snag some up.
