U - Cre8tions review for Printful: Print on Demand

I use this app to get my t-shirts to my customers fast, easy and cost-efficient. I like that it's so simple to set-up and that Printful guided me every step of the way. I think Printful needs to improve on its variety. There's not enough to choose from, not enough pants. Also, it won't hurt to have more melanated mockup models. Also, It is not a good idea to have the mockup of the woman holding the black frame to be wearing all-black. The site interface needs work. When I select only a single frame size, in my store, it no longer displays a size. This can be fixed by adding the size to the mock view. I would like to be able to put the frames measured in cm to inch with an auto calculator. When placing my designs on some mock-ups it is impossible to center. I would like to know where my design is positioned by number. Why is it when I click Back to Browser it hopes me somewhere random and not to the previous page?
