Sprite Stitch Board!

I was wondering what is the bigest size of Aida you can get at the stores? I live in America so it has to be in those kind kind of stores.. Can you get them be the yard at joanns or something?? Just wondering bulecause is been on my mind for a while...

Yes and... No. Jo-anns and Michaels both carry Aida fabric that is sold by the yard but not all stores keep it in stock (from personal experience).
For Jo-anns look under Home > Cross Stitch > Stitchable Fabrics on their website.

The easiest thing would be to call your local stores and ask. If they don't have it they can likely order it. If you can order from online then you have many, MANY, more options available.

I live in Canada but I shop at Michaels for a lot of my crafting needs. I've bought some pretty huge rolls of cloth there before. At least 4' x 2'. Probably even bigger than that. The colours seem to be a little limted there for the rolls of cloth - white, beige, oatmeal - they come pretty big!
