I can give you a few pointers. First off, make sure you really like what you do, sometimes turning a hobby into a business, makes it not fun to do anymore. Next, you need to have a plan. What are you going to sell, is it selling now? What are you going to charge, make a spread sheet up of the crafts, what it takes for each and what it will cost, then decide can you make it, and make a profit.
Next go to craft fairs, look around, look around, see what is selling.....find out what it cost to do a fair. This might be a good way to get started, plus you will have contact with people to find out what they are looking for and why.
Next you want to start making them. Whatever they are. Be diversified and think outside the box.....try to make a new spin on something or do something extra if you can. Try to be ahead of the time, which means you would want to start fall and Christmas here soon, depending on what you want to do.....
I always preferred doing shows, but it does take up your weekend......and if you are not prepared, it can be costly. I usually made money, sometimes more than others, so check out the shows and get information before you decide.....like how much traffic they have had in the past.......
Make sure you keep all receipts for tax purposes, you might need to get a retailers license depending on what Ohio requires.....plus you will have to pay taxes most likely......probably quarterly once you get going.
Setting time aside is always an issue, but if you want to do this, you can do it.....just takes planning and time well spent.
Good Luck and let me know what you decided......
