Sorry to be off topic (again) - last comment about printing/applying tissue:

There's absolutely no need
to iron the tissue onto the foam! Spray the adhesive onto the foam and/or tissue, then carefully position the tissue at an edge and smooth it on a little at a time starting at mid point, pressing out wrinkles as you go. Keep the unpressed tissue off the foam by holding the piece upside down to let the tissue flop, or (rightside up) slide a piece of wax paper over the foam and withdraw it as the tissue is spread onto the foam, or carefully hold the unmounted tissue off the foam as you press, etc, etc. Lots of ways to do it.
For glue stick, I use UHU Stic - good for "sticing" down any loose edges, among other things. Goes on pink and turns clear as it dries.
