Magnetic puzzle

[avapilot]

i have experience and the black marks are a product of the material that the magnet is made with.....no cure for that!!!!...you could try painting the sides of the puzzle pieces with black paint, using a paint pen....but that seems time consuming......later

Somebody ask me to do a magnetic puzzle.
I buy a sheet of magnet with a PSA adhesive on the back.
I glued the sheet behing my 1/4" BB and start cutting.

The magnet sheet cut well but the side of my puzzle piece have some black marks on them. I try some blade but I always get some black marks on the piece. I would like to have a 100% clean side...

I'll also try to stick the magnet after cutting my piece but I've pass a long time clean cutting the magnet with my X-acto....but the result was perfect. Long, very long...but perfect !

Do you have any experience with magnet sheet ?
The one I have is a 0.20 mil rubber sheet.

Bye !
