Thanks everyone... I think I'm going to enjoy this forum....
The 12 blocks shown are only 3 of the six colors I've chosen... I still have to make the tan/brown blocks.
Someone in another form was able to help with this idea that I thought I'd share:
i don't have a template or a stencil. i use the fan or cross hatch when i hand quilt. my granny taught me to tie a string around my marking pencil (i haven't bought one yet, but they now have one in the quilt shops that does a very nice fine line and they sell several different colored marking leads. you probably could just buy the leads and use an old mechanical pencil.)
anyhoo, you tie the string around the pencil, then tie knots in the string every 2 or 2.5 inches starting from the pencil point for how every many arcs you want. you then take the first knot, put a pin through the knot and put it at the corner of the square, hold the pin securely, stretch the string taut, and draw off your arc. do that for each successive knot and you will have your fan.
