I made a bunch of cell phone and Nintendo DS pouches for my daughter's event at school. She sold every one. Here are some examples:
All the pouches I made were from clothes I had gotten from thrifting. Most of the items were about 10 cents to 25 cents each. Each pouch I made, I got better and better. To take it to the next level, I'll need a new sewing machine. LOL. But the main thing is using my creativity and inspiration, because it sparks me up enough that my whole family notices.
