I realize this is an old post, but I was wondering the same thing..... I have a client who wants me to heat press a design on lots of 600-denier polyester tote bags.....
Any pointers on vinyl type... Will thermoflex plus work or would thermoflex extra be better? Any better brands?
Also, what sort of heat settings should I use.... I'm guessing I should slip something in the tote bag so it doesn't melt to itself....
Any other tips? Thanks!
