You can get a yard of Sosfdesigns 3d cartoon fabric at spoonflower with all these colors or pick a yard of the same color. You can also purchase just the fat quarter size which is one bag. Once you have the fabric, you use the 'drawing' of the bag as your front panel to sew up your bag. You can make it a simple tote bag or a back pack.
The end result will look a little like this!
