I am a professional footbag supplier in China. I make kinds of footbags. All my footbags are made by hand carefully, the diameter is between 4.0cm to 6.0cm. I have three kinds of filler for footbags-----sand/plastic pellet/metal pellet. There are three kinds of fabric for footbags: ultra fabric/ultra suede/ultra suede light. I usually use the ultra fabric to make footbags. I have 5/6/12/14/24/26/30/32 panels footbag.
