I found some some clamps at Harbor Freight and I use those on my circle slot ruler. I clamp the ruler & fabric to my cutting board in 2 places. They hold really well and I make all of my cuts perfectly.

Thanks for the tip about the clamps. I have used this type of ruler, and experienced slippage. I think I'll try again now.

Are you sure it isn't a ruler that is slotted, called the Shape Cutter? You'd lay the fabric on a cutting mat, put the ruler on top and run your cutter up the slot?

Has anyone else had trouble with the slots becoming nicked and impossible or should I say impassible? to use.

Aren't there videos on June Taylor's website showing how to use this? :D:D:D

It is a June Taylor cutting mat..you guys are so knowledgeable...how did I ever quilt without you? I will look for the June Taylor web site, didn't think of that.

I saw it on Fons and Porter a couple weeks ago. They maked where they wanted to cut, then just ran the rotary cutter down the slit. It looked pretty easy. My quess is that you have to have a pretty sharp cutter.

I got a NEW June Taylor ruler at a garage sale for 25 cents and had no idea how to use it. Thank You guys so much. I will try it today. I knew it was good for something. I love this board!!

Thanks for the idea to check the website! Now I have even more ideas dancing around in my head. The videos are helpful and show more uses than I would have thought of on my own.

I have the quarter inch ruler and just used it for the first time. It was a great help trimming some scraps into blocks. I have trouble sometimes with my larger square-up ruler.

I have one and I love it for cutting strips. It is quick to cut several strips. On,y draw back is that you have to add correctly when adcancing. eg- When cutting 3.5 in strips need to advance 7, 10.5 ets. Sounds silly but I have missed cut several times if not careful.
