I have designs for wallets, shoes and other things. How do I manufacture a few of them?

Hey There!

So. I have a typical day job but I also really like to design things. Mainly wallets, shoes, t-shirts etc. but my ideas are always just drawings and ideas… I’ve never done anything with them.

I’m thinking about investing some money into starting an online store where I can sell some things I’ve designed and just see if it turns into anything…

I’m actually pretty good with the computer, I could set up my online store just fine. What I don’t know a single thing about is How would I even go about creating what I design? Do I find a manufacturing company? Where do I go to outsource? Pretty much: Where would I even Begin? (with saving money where I can as a side concern)
