I have started experimenting with sticking black printed centres onto lining paper. Not ideal as the printed paper and glue don't help with clean cut holes, but for sighting to a cross written with a marker pen, the lining paper does seem to make a reasonable substitute.
When I get chance, I am going to see if I can run a sheet through the printer.
Hope it doesn't jam, I will be in the dog-house if it wrecks the printer...
