:-D :-D :-D Well on the back of the package that my 10 degree ruler came in, there is a pattern for a Christmas tree skirt and on the instructions it says to take some clear packing tape and make a little tube and place it on the ruler. I put a few small ones on mine and by golly is sure stops the ruler from sliding when cutting your wedges. I found that when you cut wedges in an angle, it helps keep the bias from stretching while cutting too. I made the skirt and there is a picture posted and that tip sure does work for me and I bet it would work real well for those of you who are doing the stack and whack and one block wonders. I like it better than the invisigrip, but take the tape off when done using the ruler so you won't have any gunk on it. Pretty neat Huh???? Have a great day, Huggies, Fay
