For a recent project, I couldn’t find any graphing paper that is of cardstock weight, so I printed out my own grid on paper. If you can’t find the time to make your own grid cards, I’m also thinking of putting up some handmade ones in store as soon as it’s past beta stage. But if you do decide to have it a go yourself, attached is a printable grid pattern I made sized 8” x 12”.
I cut cardstock to preferred size and this size makes a clean quadrant of 4” x 6” while still small enough to be fed to my printer. You can try printing on a regular 8” x 11.5” (might go out of margin) or an 8” x 13/14”.
