I make my own grid paper by using the Table feature in Word. Sometimes I do big squares to experiment with a block layout (4 rows 4 columns). Sometimes I do however many rows and columbs there will be blocks in the quilt. The last one I did was 21 rows, 21 columns. Once you get the table made, you can play around with the font size or just enter until the squares look square or go into the properties of the table and set the column width and row height. You can even go into each square and use the fill property and add color on the computer, but I think it's faster to use my colored pencils. I have grids from 3 x 3 all the way up to 21 x 21. I just go into the file and print off the page of the grid I want. Good luck finding what you're looking for.
