Opening small businesses...?

Hey guys so I wanna hear from you all that started a small business. How did you go about starting it?

I am a SAHM with a lot of time on my hands. I want to make some crafts to sell to make some money on the side since a part time job or a job in general right now is out of the question. I guess my question is where do I go from here? I have ideas and after I get moved will be starting to make those ideas but how do I start to advertise and sell. I guess I just need all the advice I can get lol so please share some experiences 😁

TIA!
