i have used a few different ones; there are a couple that seem to be readily available. the june taylor brand i was disappointed with for a few different reasons. cost was a biggy. i will have to try to find the others i don't remember the 'brand names' but there is one that comes with 3 sheets in the package...and there is a different one that has 10 sheets...that is the one i like...it runs through the printer just fine...just follow the instuctions on the package for heat setting.
