I made enough for at least 10 bags of each color (which yes, is a lot, but it means less time gathering them up after each game). Now it'll just be a matter of sewing up 3 sides, adding a scoop of beans or rice, then sewing up the other side. Hoping I made them big enough...
Sewed up a couple of these bags--so far so good. Also pinned a whole stack of them; the going back and forth from sewing and pinning was a little annoying. I prefer just doing the same thing over and over instead of stopping in the middle. So I paused and pinned them all. Next step will be to sew the rest.
Sewed together the last of the bean bags, turned them inside out, filled with a few scoops of pinto beans, and sewed them back up. Got most of them done except for a couple when I ran out of beans. Will get another bag. And depending on how the game is played, might need more bags. I ended up with 10 each, but there's enough fabric for twice that many. Will know more with some trial and error playing the game.
