A sharp pair of scissors has worked well for me. It will keep the edge from fraying as much when you cut it. You will need to sear the edge if you don't want it to unravel though. I used a small oil burning candle we had at the house. I held it away from the edge just enough to make it shrink back a little. You can use a lighter but you have to be really careful. Just take your time both cutting and searing and it will be a piece of cake.
Just out of curiosity, what are you making? Inquiring minds always like to know what new projects others are working on :).

Sharp scissors will work OK and are probably the best choice if you are making one small project but if you just once use a rotary cutter and a cutting mat you'll never go back.

Not cheap though but shop around on-line and you can reduce that pain some.

I've been thinking about one of these for my homemade projects...

Are you going to use binding tape? If you are, don't worry so much about the edge. Otherwise, you can singe it pretty simply with a lighter. In factories they use extended lighters like the ones for a bbq or grill. Just practice singing or you'll burn it up. And don't forget about ventilation...

Get a real pair of scissors like 10" flat shears (~$50)or a rotary cutter (~300) if you'll be doing a decent amount of cutting. The only real advantage of rotary cutters in cutting synthetics is that rotary cutters do cut curves faster.

I haven't tried it personally, but I've heard that a soldering gun (one with a chisel tip) works well to cut and sear the edge simultaneously.

Honestly, if you're using binding tape, aka grosgrain ribbon, over the seams, you don't need to seal the edge of the fabric. Soldering guns aren't worth the time and hassle in my (industrial) environment. If it's fabric, for example super fine 15d x 30d silicon impregnated nylon, that needs to have a set edge, i take the roll down the block to the cutter who lays it out on a 15 meter table and cuts it electronically with a heat ray.

And if you're making something for your dog, use binding tape: it will last longer and there will be less edgewise to scratch your dog...

Brian,

For years I've used a "blade" that came with my soldering gun. If you've got a wood deck on your house the slots between the planks make a great straight edge for cutting straight lines. Works great, especially if you don't happen to know anyone with a laser cutter.

Been using a woodburning set "pen". Heats up well and melts the ends to prevent fraying. Can be used freehand (if you're steady) or with straightedge for straight cuts.
I cut (melt) on a piece of fiber board.
