I want to get proffessionally cut stickers for my first mod, my hexaminx. How do I do that? Here is a bad picture.

Dr Sticker is probably your best bet, just send him designs for stickers and they will be made for you.

Alternatively, if the hexaminx is normal sized, you can get some from Olivér Nagy, he will almost certainly have them.

Congrats on the puzzle! It looks great
