This is a product we designed and produce inhouse. We do this because, after years of doing beadwork, I found the existing graph paper on the market to be sadly lacking. This paper is marked off with darker RED lines at every 5th bead and the remaining lines are in yellow. This is so your design is more prevalent than the graph paper, yet you are able to still count where you are at while you work. Every 5th row is also counted out with the number on every edge so you don't even have to add the beads you've counted. The rectangles of the graph are in approximate actual size of a size 10/o seed bead, so you can get a good idea of how large your finished project will be as well. This really is a useful tool for you beadwork pattern designers out there.
