For this project I used freezer paper templates and starched and pressed the seam allowances. Without basting thread, the freezer paper came loose if I didn't starch.
One other note: I used a ladder stitch instead of a whipstitch for the seams. I'm very happy with the result, but it was slow going and I think I'll be back to whipstitch on my next paper-piecing project.
Here'm my template if you want to give it a go:
For a paper-piecing primer, you can't do better than the tutorials and videos(!) Lynne is posting for the Lily's Quilts Hex-a-long.
