I don't know if you have graph paper grids for hexagons and kaleidoscopes and other patterns, but while I was researching what to do with all my GOOB sale templates, I found that Marti Michell has a ton of free grids on her page. (No affil, just enjoying my templates).
Go to her Tips and Tricks page here:
