Devon, I don't know what American's call what we call Calico, but you are correct - calico is a very sturdy cotton that's plain cream/unbleached in colour (tends to have little dark flecks in the fabric). I don't think it's called canvas - that's something much heavier and stronger.
You should be able to get it in a good fabric store. Hope this helps. Cheers, Helen, Aussie living in summery Denver - To unsubscribe send email to [EMAIL PROTECTED] containing the line: unsubscribe lace [EMAIL PROTECTED] For help, write to [EMAIL PROTECTED]
