I use Mac tac vinyl in a matte black finish
. Takes about 5 minutes to put
it on and you can peel it off any time you want if you want to change background colour.
Costs about $5/yd at Stanley's Sign and Screen: 456 - 42 Ave. S.E.
If you think you might go with this, let me know and I will give you some helpful hints on how to best apply it.
