Has anyone used heat n bond for appliques. Gotten some that says NO SEW BOND. Done all the blocks and notice a small stain on 2 blocks, washed tham and some of the appliques where lose.Have used this bonding before and had'nt had this problem. Tried to sew around design and needle got gummie so thats out, what can be done to hold designs on when washed, I wash everything after quilts are finished. Any advice?
