I have 2 boys - 5,3 who love playing with their leapster (they were sharing one, but we bought the 3yr old his very own leapster for christmas this year)
and I made 2 leapster custom bags for them. i used plastic canvas to make it nice and stiff inside.
front of bag with clip on removable embroidered handle:
back of bag: snap/elastic pocket for holding headphones:
bag open showing pouch pocket - zipper closure for cartridges:
zippered pocket showing cartridges (sorry it's blurry!):
inside shot showing the leapster - with cartridge attached fitting nicely in the bag:
a pic of my 3yr old approving of his new bag (his is blue; his brother's is red):
feedback appreciated. i think i incorporated all the elements i felt were necessary for a child on the go with his leapster - no space for chargers, etc but really, what does a kid bring with him on the go? just the game unit and a couple cartridges!
