I really want one but I'm way too poor. I actually found a tutorial online for one that you sew yourself, basically you just need two rectangles of fabric and you sew vertical channels into the middle and sew up along all the edges but the top. Then you fill each channel with like a fraction of the pellets (which you obviously have to buy), sew off the boxes for the bottom row and repeat. There is math involved and stuff but it seems like a cheaper alternative, especially if you can get the fabric cheap and have basic sewing skills. Maybe something to do in the future. For now I am settling for layers and layers of blankets.
