A hobby for a stay at home mom

So I'm planning on becoming a stay at home mom with 4 little ones (baby #4 is on the way). I had made some special keepsake picture frames, and I've had quite a few people tell me I should start selling some as a small at home business. What do you parents think? They would he fully customizable using the customers special keepsakes. (And I'll be purchasing a lot better quality materials to work with.)Please let me know how I could improve, and if it's worth giving it a shot. Thank you!
