I don't remember where I first saw this (I'm guessing pinterest), but I've been wanting to try this for a long time. Did you know that professional carpet installers also use rotary cutters? Yep! And did you know that they use a 45mm size that will fit your fabric rotary cutter? Yep!
Now comes the best news of all - a 2 pack only costs $1.99. CRAZY, I know!!
I would have tried them sooner but the only place I know where to find them is Harbor Freight Tools and we didn't have a store near us until now. They have very mixed reviews from quilters - some say they worked great, others say that they were awful so the jury is still out. So far, the one I put in my Olfa cutter works beautifully. I'll have to keep you posted as to how they hold up and whether I purchase more. Here's hoping, because it's an incredible deal.
