My Frog project I have in the Virtual Quilting Weekend had us make the HST in the 8 at a time method. As usual, I added just a bit more fabric and kept the proportions the same so I could trim them down to size. Here's a site with pretty good instructions:

You can make the grids even bigger if you have a lot of HST, any time I am making 8 or more of a combination I typically draw a grid. Usually though, my scrappy self says must use more fabrics!
