I’ve made a painting on a piece of 1/8" plywood, and I need to trim the edges down to size in advance of framing. I have to cut about 2" off three of the sides, and about 12" off the fourth. Because of the painting, I need to do this carefully so that I don’t cause chipping. I assume a hand saw of some sort will be the most suitable, but it’s not a set of tools I have much experience with.
Suggestions of tools I should look into?
