Have you heard of the carpet cutter blades from Harbor Freight hardware store? In another group, they are all abuzz about using them for rotary blades cuz they are so inexpensive. 2 blades are only $1.49 and the actual cutter that comes with 3 blades is only $3.99.
But the cutter doesn't look like it would work for cutting fabric beside a ruler for cutting guide. Can't help but wonder if the blades are more durable since they are for cutting 'tough' carpet. The blades do not have the 'notch' in them that most of our rotary cutting blades have.

guess the best thing to do is to go see if they'll work, they aren't expensive. I hear that that are now on back order online...wonder if it is cuz so many quilters have ordered them, LOL.
I'll see if hubby wants to go to one of his favorite hardware stores :D
