I'm looking to economically cut up some magnetic numbers for autocross. I already printed some numbers of appropriate size and font to use as stencils, just need to buy a blank magnetic sheet of 2'x2' with vinyl outer layer and I'm ready to cut. Dealt with a supplier who work from an Airdrie home last year but it sounded like they are no longer in business. Where would I buy such sheet in town?

Price range of $20 - 30. Either white or fluorescent lime for color.
