Can I sell Chanel inspired Jewlery that is not from Chanel but better?
You should write to Chanel for clearance to do so, you don't want to be sued if they find out. Since the jewelry looks exaclty like Chanel, it is trademark infringement. You will be sued.
Wallet printing, vinyl, HELP PLS?
You do your design then get a block made at an engravers. You can use gold ink or whatever colour you want. I would suggest linoprint ink.
Help me find a non-leather wallet online?
you can always try veganessentials.com or some other site like that, though I'd imagine buying these things online could get fairly expensive. I'm sure you can find some nice cloth (non-leather) wallets in areas around where you live...I have been to...
