You do not have to go to college if you want to crochet. I think there are some great ways that you could make some money. You could open an Etsy Shop or attend trade shows/local fairs. Another great option is you could look up events in your area to see if you could sell your crochet items. People love custom or one of a kind items and usually are willing to pay more for such items. If you can differentiate yourself from others that will help your business grow.
Good luck and hope this helps!
You do not need to go to college to crochet for people. Your challenge will be determining how do you see yourself using your crochet skills? What will you make and sell? There is an opportunity for you to be self employed and sell your products, depending on what you want to sell and to whom. You should also check on industries and companies that have products that you would like to create.
