The template is for a pattern called circular patchwork, it looks like an orange peel pattern or robbing peter to pay paul. The template has heavy metal with a rough side so it won't slip on fabric. I'll see if I can just use the templates at the size they are ..

Trace the template onto card stock or cardboard, or whatever you are using to make your template. Then tape two pencils together, you might have to try different pencils or pens markers whatever to get the leads 1/4 inch apart. Then place ONE of the leads on the line and trace it making sure the other lead is touching whatever you are using to make the template. You will have an exact copy except one will have a 1/4 inch seam allowance! I have done it this way many times.

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.

Mark a series of dots 1/4 inch from the edge of the template and then connect the dots or find a plate or lid that meets the right dimensions to trace around. It's amazing how many "templates" a kitchen holds.

somewhere i have a tiny medal flat circle with a hole in the center. it's made to go around templates adding the seam allowance.

A washer with 1/4" from outside edge to hole edge would work, too.

I have that set, I just used a pencil and traced around the template and then cut out both circles. Since the seam allowance is totally on the inside it doesn't show so you can just guesstimate your seam allowance.

If you are making the small ornament sized one, I did find that it made a better ornament and turned nicer when I used interfacing on one of the circles.

I just used the square one for pressing. Did you buy the pattern. I have to admit I found it annoying that it came without any directions.

If you can't find the doodad nativetexan referred to, get a 1/4" button.
Butt the button up against the template, put the point of a mechanical pencil into one of the button holes and zip that baby right around the template.
