You have the right idea to add something underneath. Make sure it fastens properly and doesn’t tear your work apart. Have fun.

Yes, my mom through making costumes for the theatre. She had to make a skull shape out of metal studs so it was heavy. this was her advice:

Use interfacing, the iron on is best, using two layers if you think it needs it. Remember though, once it’s ironed on, the part with the interfacing WON’T stretch. Take into consideration how often the piece will have to be cleaned as some dry-cleaning solutions wreck the solvent glue in the interfacing
