I think those little tab things make the mat not level.
Just my opinion!! lol

simple quilter

cheap emry boards place under coners if a big mat then put under the middle sides

In my beginning quilters class we were taught to "walk with our fingers/hand" along the ruler as we cut. This tended to keep the ruler from scooting around on those longer strips. Also have the little sandpaper discs. Every once-in-awhile I go off track...wasn't focused. (Hate that!!!)

There are stickies you can buy for the back of your rulers. There is a suction cup type holder too you can buy. Your mat should not slide. I think this is why Ilove the new Gingher mat--they are so self-healing and don't move.

They have a "handle" that suction cups to your ruler that I hear people have great success with - it's also easier on the hands that have arthritis, carpal tunnel etc. Another thing that can help is to get a ruler that has a 'lip' on one end...this way you can butt that up to the edge of your mat and it won't slip and slide! Best of luck....keep practicing - sometimes that's all it takes!

John Flynn used to make and sell a "ruler/straight edge" called The Cutting Edge which helped solve the problem of a ruler moving against the cutting blade.
It was a full length/24" long, 6" wide straight edge - no markings.
You measure from the right, butt the "edge" up against the ruler, and cut along the non-moveable "edge".

I can't find it now on his web site but have sent an email asking if it's still available; will let this thread know if I get a response. It was a very helpful tool for my beginner classes. And it's great for older hands with less strength to hold that ruler down.

i used one of those rolled up rubber mats that are sold everywhere..usually in the kitchenware near the contact paper..cut to size and your mat will never move..on your rulers buy grips and put at least 9 on there..and that should do it for you..

Okay so I wen't to Home Depot and Rona and they do not sell clear sandpaper for the back of my rullers. Anyone know where to buy invisi grip for my rullers? Would Fabricland sell it?

That is weird that they don't carry the sandpaper dots. Even the dime store has it here. So does home depot and lowe's and the grocery stores in the home fix-it type aisle. We don't have Fabricland anymore they turned into JoAnn Fabrics. Good Luck!

Aully, the sandpaper discs are brownish color. The clear part is the backing (it is smooth) put on the ruler before the sandpaper discs. I THINK it is called Magic Cover, but am not real sure.
