I've been scouring the internet for ways to make this. Basically the general I idea is: buy some sort of solid material then fill it up with play sand or some sort of sand. Well, I'd like a second opinion! As you may have already assumed, I can't afford a legit heavy bag right now, but I'm looking into alternatives. If any of you good folks here at Saddo have suggestions on how to make your own or have made one in the past, I'd be more than receptive to your knowledge. Thank you ahead of time!
