Here is the lovely Aimee sitting on her newly made Squirtle Pokemon bean bag chair. It takes about 2-3 meters of fabric and 2 bags of Styrofoam beans, bought at Wal-Mart.
Cut 6 side panels, a top and a bottom. Sew the side panel together leaving a hole in one of the seams to turn it out and add filling. (You can also add a zipper here too.) Add on the top, then the bottom. Stuff. Done. Side note: I added some arms and a round squirtle head to spice thing up.
