I agree with this suggestion. I think this might work so that you can salvage your work. I feel your pain and am sending you hugs.
One suggestion: Try to find a lightweight iron on stabilizer or interfacing and apply that to the back of some fabric and one or two of your existing blocks. See if that gives enough strength to go on with. In a book I just acquired, the author recommends Sulky Soft 'n Sheer stabilizer.
Good luck![/quote]
