I was going to purchase some of the alumamark product to do a 50th wedding anniversary plaque (Gloss Gold). No problem until I found that it comes in a 12x20 inch sheet and requires being sheared to the correct size. I don't have a metal shear and have not had enough business in this end of the business to warrant the purchase of a shear yet. The material is 0.020 inch thick. Has anyone had the same problem and if so, how did you resolve it and get a clean edge? Not looking for a cheap fix but inexpensive would be nice.
