I am working on a project that has taken on a life of its own.... I have used 40+ yards of pellon fusible interfacing ... with no problem. It fused well and all went as planned My problem is that the last 5 yards or so just is not fusing. I don't know if I got a hold of a bad bolt or what the problem is... my question is can I just use this as is? I have spots that are fused and other spots that are not. If I sew this in my quilt (back of a T shirt) will that work? I am frustrated and not sure I have the patience to iron again. what do you think?
