Interfacing is one of the things that can transform your fabric and make the difference between a home-made and a fabulous fashion accessory.
Its not to hard .Once you see the effects of quality interfacing applied properly, you’ll be thinking “interfacing” as soon as you think the word sewing
This mostly happens with heavier interfacings, and is usually a result of one of the following –1. The iron was not hot enough.
Pre-washing fabric reduces the likelihood of this issue, although sometimes there is an incompatability between the dyes or fibre in the fabric and the adhesive.
5. The fused fabric was moved while it was still hot.
Leave the fabric to cool (and the adhesive to set) before you wriggle it around or sew it.
The manufacturer’s directions often say to leave it for up to 30 minutes…..
so at least let it cool!
3. If your interfacing has shrunk and bubbled, you’re best to rip it off
