K-pop Handmade Merchandise Store

Hi! So this winter, my family and I are going to Korea for sightseeing, the food, and because of my love for k-pop. I want to save up some money for the trip, so I decided, "hey, I want to make and sell k-pop related things, so why don't I try and do that to earn some more money?" and now that's exactly what I want to do. I would like to make metal bracelets, t-shirts, and resin charms. I am already experienced with most of these as well, which is a huge plus. I would like this as soon as possible, as winter is coming around the corner, and I need time to create and sell. Thank you to everyone, even if you only read this, but please help even if it is only a $1! It would be greatly appreciated.
