I used an iron set on "cotton"..which is hot,I think=), applied it directly onto the veneer..started at one edge moving fairly slowly, with a small block of wood in the other hand, to follow the iron and press the veneer down. It sticks almost instantly, just use the wood block to press and hold while it cools. If you make a mistake in postitioning etc, just reheat, and the glue softens again, allowing you to move it=)
The panels I veneered were slightly narrower than the width of the roll of veneer, so I didnt have to join any pieces, just lay it flat, trim slightly over length, and iron on.
The veneer came with some instructions printed on the back on a label..that I found after I had finished.typical=)
After 24 hours or so, re-check for any bubbles that might have popped up..just iron em flat again.
As I said i'm no expert.This was my first try at veneering and it worked out fine........ but I didnt have to join pieces to get the width etc, which *might* be tricky..hopefully someone that knows might chime in and help=)
