I'm making iron-on patches for the christmas market this year.
For that, I recently bought some wonder-under in Japan ("melt fuse" by Japan Vilene Company).
It's different from the Pellon brand I'm used to which is not at all stuck to the non-stick sheet it's sold with. The glue activates easily, with a touch of the iron.
This Vilene Melt Fuse I bought is a thinner webbing and is quite attached to the nonstick sheet. It also needs more pressing to activate the glue. When dried, it stay sticky to the touch. Looking at the drawings included with the directions, I'm worried that I'm expected to do a whip stitch around the applique to reinforce it. That of course, doesn't work for the iron patches I intend to sell.
Has anyone had experience with wonder-under that behaves this way?
Is there someone out there able to decipher the directions, especially step 4 and the warning symbol at the bottom? My winter project and I would be very grateful! We're really in a jam!
