I'm a newbie at quilting and i joined the BOM the owner is very nice .A friend of mine suggest i do this and she has been great in helping me when i get stuck or discourged.I tore out my blocks 4 times and then just gave up she told me to bring it to her and she would try to figure it out.She measured all my 1/4 seams and they where on but my whole block was off.We came to the conclusion the reason its off is that i tore it out to many times and stretch the fabric. I hope the next one i do comes out alot better then the first one.But don't get discourged pratice does make perfect.
