Need these for a large motor skills kid's game? The goal is to help with math including rolling a die outdoors. First, the dice needed were: two 6-sided dice and one 12-sided die (a dodecahedron). A beanbag for hopscotch was the easiest need to sew. The 3D print failed so sewing it is!
Step 1: Select Material
The panel comes from a reusable shopping bag. Lots of uses for the tough, water-resistant material.
The blue die came from the side panels.
The dodecahedron material came from the bottom panel and pocket
Step 2: Cut the Base Shape
For the pentagons of the 12-sided die use a paper cut-out and tape to cut each identical piece.
The bean bag and regular dice are a simple square.
Step 3: Sew
Lay each base shape piece outside-to-outside. The dice only get one edge addition at a time and have 3 pieces to a corner.
For the bean bag example: use a sewing machine (or by hand) to stitch around 3 edges of the perimeter, 1/4 in from the material's edge. The top right and bottom right corners need stitched around the corner 3/4 in into the open side to reinforce for turning out the beanbag.
Step 4: Sew Inside-out Shape
Continue adding base shapes with the outsides all facing the center. Leave one edge open.
Step 5: Stuffing
Use a shredder to upcycle magazines. The glossier and heavier paper, the better. Turn out the shape. Stuff with handfuls of shredded paper. Alternate every 8 handfuls of paper with a small handful of dry beans.
Step 6: Finish
Tuck the open edges into a seam and hand-sew the beanbag shut. Add dots/numbers to the dice with a sharpie. To get better shape and versatility from the 12 sided one, make cardboard stock pentagons and hot glue to beanbag die. Roll to your heart's desire.
