I use something called Triangulations, it's a CD that has PDF files of HST and QST in many sizes, you just pick the size you want and it will print out the sewing and cutting lines for you. The smaller the size the more will fit on an 8.5 by 11 paper, but you can print out as many as you need. If you want to use strips, you can use those as well with Triangulations. I like that I don't have to keep buying something, just print out more. And you can use any paper that will go through your printer, like Carol Doaks Foundation Paper... works great for HST and any other Paper Piecing projects.
