I don't use either. I print my hexies from a site on the comp. (texasfreckles.com is a good one) using mostly junk mail paper, and cut them myself. I usually have a few pages printed up so I can cut a page or two at a time. I just stright pin the papers to the fabric, and baste. Goes pretty quickly. I think the precut would be nice, but don't think there was such a thing when I first started doing GFGs. Keep thinking to try the freezer paper, but just haven't gotten my round tuit yet! What ever you do, enjoy the process. WARNING it can be addicting. :)
