I was surprised at how well it worked!
I experimented on a really old rotary cutter and blade. I've been using the blade to trim paper for 2 or 3 (or more) years. It works fine for paper....
|If you look closely you can see that it didn't cut the fabric very well. I should have used a different color (duh!), but you can see in the photo that there were a few places that the cutter didn't cut the threads.|
|I folded up some aluminum foil. I think there are 8 layers in the photo. I don't think it matters too much how many layers there are, but more than one layer would probably be best.|
|I used the newly sharpened rotary cutter to make a new cut to the left of the old cut. |
It sliced right through the fabric!
I think I'll try sharpening an old pair of scissors next. I have a pair that don't cut through plastic bags any more, so even if the aluminum foil trick doesn't work, it can't make them any worse than they already are.
