First post! (finally) /shop help?

Heyy all c: my names Scarlet (for reals lol) I’m still sort of new here but I’ve been getting the hang of games and the site in general. It’s been really fun and I’ve enjoyed getting to know some of you! Hoping to meet more and make some more friends along the way <33 I’ve been thinking for a PHAT minute about how cool it would be to make designs, I absolutely LOVE fashion and I wanna make stuff irl eventually too lmao. I was hoping to get some tips on how to/what to use? And if it’s even possible to make designs on a phone potentially, cause I don’t have a pc rn lol :’) I’d love to make custom designs and sell/gift stuff to everyone too! c: <333333
