There used to be a rubber thing that held two pencils side by side to add seam allowances. you can probably get the same result by using DUCT TAPE (lol!) or masking tape to hold them together. Worth a try. If you have one of those 1/2" rulers to divide squares into triangles, the center slot is 1/4". You could put your pencil in the slot, and pivot the sides around your circle template.
