I use Triangulations software. No marking, no work, just sew and cut along the lines. There's also available for FREE a version from quiltingandwhatnot.com. Quilt-Pro also had their version for sale for $9.95. Don't know if it is still on sale. I LOVE using Triangulations! If I don't need a full page of whatever size, then I just cut the paper in strips or half-pages before sewing. When you cut along the lines, you also cut the dog-ears off so there's no going back and doing that later. Triangulations works wonderfully, and HST come out perfect every time.
