We tested it out. Worked on one specific garment we did, didn't work on a few others - no discernable difference often. I do remember testing pressing with polo material vs parchment paper and seeing a bit of a difference. So, it's definitely possible to press in something different and get a slight pattern / different feel, but very difficult to achieve a good result and hit or miss based on the garment it seems. 99% of people won't notice the difference when you are able to make it different imo. Not to mention following the directions means it will take longer to print (to evaporate the liquid largely).
