You'll find that in order to fully blend in without the use of any magic, you will need to carry some of their currency. They often carry it in a small pouch called a wallet.
You can customize it with a Cricut and some vinyl (I used glitter black and white)
The two fonts are "Chloe" (Muggle) and "Easton" (money) Click here for the Cricut Design Space file.
Simply cut the two words and apply them to the wallet with transfer tape. Read through this post for a detailed tutorial on how to cut vinyl.
