Sometimes I see stuff on marketplace and often free stuff that people are looking to get rid of that they made to make space. Recently I saw someone posting things they made intentionally to sell.. You can try searching items you have and what you can do with them.. Years ago I wanted something similar to coasters, but supersized b/c I didn’t want little coasters everywhere(kids) and I wanted to be able to put a plate that was hot on it so my expensive coffee tables wouldn’t get ruined. So while searching I saw little coasters that gave me an idea and I use them every day since in a few different rooms. I made more before Christmas and my mom one as a gift since she was saying how much she liked it often.
You can get lots of ideas seeing stuff you don’t even want or like.
