(This idea courtesy of Dr. David H. Grosof - visionary, trivia master and all around mensch. One day he walked past me as I was aimlessly embroidering dozens of copyright symbols and asked "Copyright and copyleft gloves?" And at the moment it was decided, "Yes. Copyright and copyleft gloves.")
Step 1: Go get stuff
A Singer Futura embroidery machine
A sewing need
Step 2: Prepare to embroider
Step 3: Prepare your image
It should be ready to send to the machine.
Step 4: Embroider
Hit go and let the machine draw embroider a copyright symbol.
When you are done, on your computer file, drag and release the copyright image to the left such that it clears the first image. Save the file and then send it to the machine again. Hit start once more and embroider a second copyright symbol.
Step 5: Cut out your patch
Cut away the jump stitches left over from embroidering.
