I am a big fan of the Triangulations program, and use it all the time. It is a way to generate HST or QST papers to print yourself at home. Very well marked too. Then you sew up sheets of the units, it is the most speedy and accurate way of making HST or QST units. There is a test page you can try:

You can get the program on Amazon.com now too:

When I feel like sewing but not thinking I generate sheets and make HST's, throw the completed units in a drawer and when I have lots I just put them up on a wall and start designing. Great for baby quilts!
