use scotch tape to fix top of FP piece to normal printer paper, or attach to printer paper by just ironing the top 1/2" or so of the FP. Place it FP side down in copier and let 'er rip!
I do one at a time and you can easily use the same few printer paper pages and attach more FP.
If the shapes are small enough, make a copy page with several of them on it, then copy to FP.
Good luck!
