I use this free printable graph paper. One can create any size following the directions. I print mine onto freezer paper cut into 8.5 x 11 sheets making sure I print on the dull side of the freezer paper. Yes you have to cut them out, but they are free! Not only that one can press the shiny side onto the wrong side of your fabric and reuse the template 2 or 3 times or until it doesn't adhere to the fabric. Use card stock to print on and you get a more rigid template. Make sure you use the same type of for each project as there is a difference in thickness between paper and cardstock.
