Basically, I am a dumbass and can’t figure out ebay shipping

I wanna make and sell jewelry on the side, cant do etsy or shopify at the moment

Can I just tell people who are interested to dm me on Instagram and have them PayPal me the money and then I ask for their name and adress and ship it that way? Ebay doesn’t offer the shipping services I have available in my area

And by can I, I mean will I look like a scammer? 😅

One more question: because it wouldn’t be a big business, can I sell the jewelry i make on vinted? I feel like it makes things a lot easier for me and the buyer. Thank you!
