I have a 2" hexagon GFG in progress. I use freezer paper & Kaye Wood's 60 degree ruler to cut the freezer paper & strips of fabric. Here is a link to a pdf file explaing her method:

I pin the fabric onto the freezer paper instead of thread basting it and I remove the pins and papers when they get surrounded by others. The freezer paper does get floppy after a while but it's good for 5 or 6 rounds at least.
