Loving it
Style: Cap & Heat Press Bundle
The printer is a really good one. After several attempt to get a really good print, I found out you have to have a png design saved at at least a 300 resolution. The heat press seems good but after ruining two kids shirts because I had it set to hot and the pressure was down instead of up so I was applying too much pressure and then trying to figure out why there was blue all over the shirts, I realized the blue silicone pad is what's leaving blue all over the shirts. To combat that I put parchment paper hanging clear down over all edges under the shirt, in the shirt then over the top of the design on the shirt. Finally I had success. I don't know if the company has better silicone pads but this one isn't that good if it bleeds all over.
