OK! I made a batch of shirts using the transfer paper from Michaels, probably their house brand.
I modified the specified application technique as follows:
The application was done on a hardwood table, not an ironing board
A piece of baking parchment paper was placed under the shirt to prevent sticking to the table
A piece of parchment paper was laid over the transfer to prevent slippage
The iron was as hot as it could go at linen setting
I pressed really hard when doing the application, possibly 30 LB. ?
So far my shirt has gone through at least two normal washings with the rest of the laundry, with the exception of being turned inside out.
No visible damage to the image.
You guys were no help with answers to questions that weren’t asked. I finally had to do my own experiment.
Lucky for you, it is now clear how the shirts can be done. My cost was less than $6 per shirt. The best quote I got professionally was $25 each. If my shirt goes to blazes, it can be duplicated 3 times and still be money ahead!
