The TRF green foil, paper, and white foil are available separately,
Mouser electronics stocks them.

If you have a good way of transferring the pattern, then you may not
need the paper. However, if you are doing toner transfer, then I will
recommend the green TRF foil, it does seem to help, and it does give
you a better idea of the sanctity of the toner layer beneath.
