do you HAVE to have the "spinning star" triangle papers or can you use any half square triangle paper?

There is a link to a site that has PDFs for different size HSTs. If you do decide to print your own after clicking on the printer in the upper right hand corner make sure you change the PAGE SCALING to NONE!
I printed two pages, cut the extra paper away from one, cut two bars from the other, layed them on a clean piece of paper and taped them down, then scanned it into the computer and I can print 15 blocks (30HST) at a time on one sheet!
