I saw something like this on Pinterest, with the purpose to be a makeup bag or pencil bag.  I thought this was something the girls would enjoy making and would be a fun way for them to stow their traders.

Supplies:

• Ziplock bags with sliders
• Fun Duct Tape
• Sharpie

Instructions:

• Write your name on the label portion of the bag.

• Start taping.
• Do the side edges last to clean finish.
• Fill with crafts and traders
