The cutting mat in the video is an Alvin mat that was originally bought for art, not quilting. I also have a green Olfa (I think) cutting mat.
I have several brands of rulers. The ruler in the video is a Quilt Sense ruler. My favorite is an Olfa Frosted Advantage; it doesn't slip and it easy to read on both dark and light fabric. I also have rulers by June Tailor and OmniGrid.
Different brands of rulers have different strong points. Only you can decide which one you like best. I have seen two others that I would love to try. One is the Cutting Edge ruler which actually sharpens your rotary blade as you cut. I would love for them to send me one to review, preferably a 6 1/2" by 24" OR a large square. (just sayin....)
The other I would like to try is the True Cut ruler by the Grace company. It needs the True Cut cutter to work properly. It has a track on the ruler that the cutter rides on to keep your cuts true and straight. Again, if the Grace Company would like to send me one to review, I would be most happy to try it and give an honest review.
