I got the idea from looking at cardboard and wantng a duel disk. I figured, waht the heck, and from there I just put the pieces together.
My computer has no way to upload pictures so I had to make everything on paint for examples.You have been warned!!!!!!!!!!!
Step 1: Gather Materials
~ Cardboard (And lots of it!)
~ Small calculator
~ String or Velcro (To fix this to your arm)
Step 2: Cut the Pieces
In other words:
~ One long rectangel that yu can place 5 cards on
~ 15 small and thin rectangels
~ One half cirlce that will cover your arm with space to spare
~ One deck box with a door in the front (or as it gets smaller from drawing the deck falls)
~ Cut the velcro so that it will go around your arm and have space to stick to the disk
Step 3: PAINTING TIME!!!
Step 4: Piece This Together!
These pictures should help if you do them in order.
