Tell us the size you want and the fabric you are using — Beanbag Studio calculates the exact fill weight, the right ratio, and which fill type keeps its shape longest. No more leaks, no more lumpy balls.
Formulas tuned on thousands of real juggling beanbag recipes — weighted for fabric stretch, fill compressibility, and throw feel.
Stretchy fleece behaves differently than ripstop nylon. Each recipe adjusts fill weight and ratio for your specific fabric.
