I use Invisi-grip. It works well.

Two things:

I use Steady Betty ruler strips. They're little pieces of foam and they grip really, really well.

Second, I do the same as Ghostrider. Put your left hand on the ruler and with your right hand, start cutting at the bottom of the ruler, moving up and away from your body. When your hands are even, stop cutting. Do not lift the cutter, just hold it there, and walk your hand up the ruler, keeping pressure on it. Do the itsy-bitsy spider thing. Repeat the process until your cut is finished. The trick is to not have your cutter hand pass up your ruler hand.

Hope this helps!

I put True Grips on the 4 corners of each of my rulers........this is one quilting notion that is worth its weight in GOLD because the rulers just do not slip or move.......Most LQS carry these,,,,,,,,which are made by the Grace Company, and also available on their website....

Good Luck!

I use basting spray on the back of my rulers, then wipe with a paper towel and it will stop slippage. You can still see through your ruler. If you get too much build up, you can use fingernail polish on it, it will build up from the fabric itself.

I know I've said this before but I love the Quilters Slidelock ruler! It will not slip and your fingers are always protected from cutting.

I use the true grips also and when cutting I cut with my right hand, my left hand holds the ruler with one or two fingers off the left side of the ruler. Also, don't cut all at once, cut, then move your hand up the ruler and finish cutting.

I tried the round sandpaper discs and still had slippage. I started using rubber cement and have never tried anything else. I can just rub it off and reapply when needed. Of course the drawback is the drying time. I apply it at night and it is ready to go the next morning.

I use a ruler with a lip at one end and put a stripe of rubber cement at the opposite end. I've tried little pads, but they raised the ruler up from the fabric and I wasn't able to grip it well enough.

I use sandpaper sticky circles, but I also keep my little finger off the edge of the ruler on the table/fabric and move my hand down the ruler as I go....only cutting portions as long as my hand then creep fingers up(like a spider) and continue cutting w/pinky off edge......just the way I do it...might help

I bought plastic dots for the undersides of my rulers. Can't remember if I got them at a store or online. The ones I have are not True Grips. I like the way these dots work. I put one in each corner and one in the middle of the long side of my rulers.
