Cutting Odd Shaped Foam Board
Decorating By SweetOccasionCakes Updated 31 Jan 2009 , 9:09pm by peg818

So I've just discovered foam board and I tried my hand at it and yeah, I'm not so good! I cut an oval and it was no where near a neat edge! How do you do it? I used an exacto knife, but it still pulled chunks from inside the board. Any suggestions?

I used to have the same trouble.....then I discovered a great tool by Walnut Hallow..."creative hot mark". It has different tips one of which is a knife. You plug it in, it gets hot, and it melts right through the foam.
Works like a charm. I got mine at Walmart but I've seen them at Joanns too.

I use my kitchen shears & they do an amazing job (they're J.A. Henckel). Kitchen shears are typically pretty sharp, and it's so easy to cut the foam core with them. A box cutter also works really well because the blade is longer and will go through the foam core better than an exacto. If you use a gentle, gentle sawing motion with the box knife and keep the blade in the foam core as you cut, it will do much better

Thanks! I think I saw you post this before on a similar question! I look for one tonight!

I cut mine with an exacto knife. It takes some patience, but you have to make more than one pass. With a SHARP exacto knife cut a deep enough groove on the first pass so that it makes a guide for the second ( or third) pass. Then you don't have to buy another tool.

I use a hot knife or a serrated bread knife. The hot knife is an amazing tool!! It not only slices cleanly though the paper, it also melts the foamcore so it's a clean, sealed cut. I freaking hated cutting foamcore board with a regular X-acto knife.
With a coupon, you can pick up a hot knife at Michael's for like 8 bucks.

I have an oval & circle mat cutter its made by Logan and cuts circles and ovals nicely and evenly It is expensive ($90) but with a coupon (michaels is where i got mine) it was 1/2 price. For all other odd shapes i use a exacto knife with a fresh blade.
