I have a design with 2 layers (for different colors) that doesn't come out perfectly lined up on the shirt.
No matter if I use tape, mounting spray, frame-they line up perfectly when I put the 2 film paper together BUT once I apply the paint for the second layer on the shirt it never comes out correctly aligned with the first one. (1 layer is for design, the other is to outline it) I wait for the first layer to dry and I don't think that I overstretch the shirt.
What can I do to have these to work? I have designs with 4-6 layers.
