I made this awesome gold totally functional messenger bag for my pokemon trainer costume in June for AKON Dallas--inside zippered pocket, cell phone pouch, pen and pencil pouch, etc. I loved it so much that after the con, I used it all summer as a regular purse! I even took it with me to my nannying job.
Of course, the little 10 year old girl I was nannying LOVED it (and pokemon) and asked if I could make her one, but in pink. So one week I brought my sewing machine to her house and for an hour a day during "arts and crafts" time, we worked on making her a bag like mine. And here it is!
The pink pokemon bag! It's made from sturdy cotton twill, the white part is really soft flannel.
outside/inside pockets are the perfect size for my cell phone. Pencil holders are under the front flap. There's no closure, just the flap
