I don't think you would be happy trying to bond fabric together this way... it would probably unravel and not look very nice...
I take it you don't have enough fabric to cut the rest to make up for it? If not, and your heart is set on this fabric you may have to bite the bullet and get more.
If you can't find any? You can try posting a picture of it here in the Classified section, and see a member has some and would be willing to sell it. :D:D:D
