We're always shocked at how expensive bean bag chairs are in stores. They don't have structure or complicated construction and are made from relatively inexpensive materials. What gives? If you're even mildly handy with a sewing machine, it's quite easy to make your own.
Our favorite tutorial for this project can be found on Making It Fun, the blog of Michael Miller fabrics (the bean bag chairs here are seen in fabrics from their Dick and Jane line). You primary materials will be six yards of fabric and bean bag pellets (from craft stores like Joanns, Michael's, etc.). The tutorial has tons of photos so you can follow along at every step.
