Watch out for your rulers! I took a few nicks in the ruler the first few times I used mine until I got used of the blade.

Ditto! I don't like nicking my ruler.

Yes, I have one and use it occasionally.

Me too. That way it won't interfere with straight cuts I make on the 'right' side of the mat.

Olfa makes one and I love it. I wash my material before I quilt it (I know let's just not get into that discussion here) and I use the rotary pinking blade to shave off the cut ends of the fabric. It does a wonderful job and doesn't fray when washing and going through the dryer. I found when I first started and washed then it is easy for me to know which fabric has been washed by the rotary cuts on the ends. I do iron the fabric when it comes out of the dryer and sometimes it is hard to tell which is new and which is washed but with the zigzag ends, easy to tell.

i use my pinking blade every now & then- i've never damaged my cutting mat with it..it is pretty sharp- you do not have to push down hard to use it. It comes in handy when i have a fabric that the edges want to fray.

I have one by Olfa, and it works great. But do use an old cutting mat, or turn it over when using these blades.

LOVE this idea. It's always been a dilemma for me & I like the idea that it keeps the fabric from fraying! Thanks for this great tip.

Canada Kate, I had wondered about this, but i just couldn't imagine how to measure the 1/4" seam. It still seems to me the inside of > next to the ruler would be the place to measure from since that is where the straight cut would have been. But I am definitely going to experiment with this. Thanks for the info and demo.

Does anyone besides Olfa make cutters that take them? I refuse to buy an ergonomic cutter just to accomodate the specialty blades and that's the only Olfa cutter they fit.
