Have just made 40 hoodies for my daughter's school. MDP hot flex. Pressed for 15 secs at 160 as instructions. Have had 2 people saying that the vinyl had lifted after a wash. I gave instructions to only wash at 40 degrees, inside out and do not iron directly on the vinyl.
Any ideas? This was my first big job and now I feel sick with worry that it has all gone wrong.
