How do you cut craft foam at home? Here are tips posted from the ThriftyFun community.
Whenever I need to cut a piece of upholstery foam for chair cushions or a craft project, I use an electric knife instead of scissors or a regular knife. Makes this job so much easier.
Mark Your Cutting Line
You can cut foam with an electric knife. Be sure and mark your cutting line before you start. I recently did this for a window seat cushion and it worked beautifully.

A few years ago, we made cushions for a bench/bed in our van from a 6 inch thick foam mattress. We cut the mattress into 4 cushions to use on the benches with a table that converted into a bed. We used a circular saw to cut the foam. Made for a quick and clean cutting job.
Large Kitchen Knife
Use a large, very sharp non-serrated kitchen knife and cut in long strokes. Makes a nice clean and straight edge.
Use A Serrated Edge
I have used both an electric knife (which has serrated blades) or, with less success, a regular serrated knife
Do you have any more ideas? Feel free to post them below.
