To keep your rulers from moving when rotary cutting, try some INVISIGRIP CLEAR NON SLIP BACKING FOR RULERS. It is manufactured by Omnigrid. I bought mine from JoAnns and it works great to keep your rulers from slipping. You could probably use some cling vinyl, which is what InvisiGrip basically is. It would be cheaper to get this product than to purchase new rulers.
Even if my numbers go the right way, my brain doesn't always. So after many mistakes when cutting. 5 1/2 instead of 6 1/2 etc. etc. I use a piece of blue painters tape on my ruler at the right line. and if I can reverse the ruler accidentally I mark an arrow on it showing the right direction. If I am squaring up blocks, I use two strips of painters tape to show the right corner. (my square cutting rulers have a half inch added to the measurement on two sides but not on the other two -- easy to get confused for me). Usually I am only cutting one project at a time so this works well for me. It is especially helpful when I get interrupted in the middle of a project and can't remember what I was doing when I come back. Distractions are my worst enemy in quilting so any trick I can find to help me remember where I was at is good. Ann
I can use the ruler fine its just that when making cuts the numbers count down( 6, 5 4 instead of 4 5 6 ) instead of up on edge of ruler closest to me. Makes it easy to make mistakes. That's why I tend to flip the ruler over.
Amoret, I think PD Quilt is talking about the rotary cutter. It has a handle that goes off to the side. If you are left handed you would need one that has a handle that goes off to the left side. I have a right sided one and it works well but you have to buy their blades for it or it doesn't work well. I think the original question was about rulers and I don't understand either since I just turn mine around and it works for either hand.
The Martelli rotary cutters come in both right and left hand models. They are different than the usual rotary cutters - google it and you'll see why. Then, I would google "left handed rotary cutters" to see if you get any other suggestions.
Is there a place that has rotary cutting rulers for left handed people.
Most of the time I will just flip the ruler but they do seem to slip more easily when I do this .
