I only make those ones with the names on in 2" wide mate, the letters are cut out of the top layer, which shows the layer below, they are cut out using a heat tool so the edges don't fray of course, takes fooking ages to do.
I make collars for terriers thought, but normally just plain colours and they are around £13 each inc postage for ones with solid brass fittings.
sounds good pal. i will pm you on friday
