I've also got a print of my Ultimate one, and wrapped it just cause i wanted to prep one just in case lol.
I print out a template to make the handle hole for the bag and then i thought it would be a cool idea if it had a design inside so its simple outside but its got the details inside. It might be costly but you know what It's very personal right now and i'd love to make them in the future, i'll just make it with cheaper costs. I glue it on there so the bag as more support on the handle when its being used, without it the bag is kinda flimsy.
That's it for now, i'll post some new artwork tommorow ^_^ peace and love everyone!
