Choose your favorite design and make your cellphone case for yourself. But the coolest thing is you can also give a gift to your best friend because everyone likes cashing and handmade gifts!
All you need is a few plain or transparent telephone casings, and that's it. The first idea is very funny. You can copy the cream on your cellphone case and make a cool candy design. You can also use resin (if the case is transparent) and small statues (you can make it yourself from polymer clay).
