About 20 or 30 white plastic shopping bags.
Two wire frame clothes hangers
Lots of clear tape. I used narrow tape but also used some wide packing tape.
Black permanent marker.
Step 1: Making bones.
Here's a tip, if you have a problem with the company logo showing through the plastic like i did, try the method in picture number 4. Cut the bottom of the bag off. Re-flatten your bag with the writing on the lower side of the bag. This way when you roll it up, all the print is as far inside the cylinder as possible.
If you would like longer bones, use two bags overlapped for extra length, as shown in picture number 5.
You will need 4 arms bones and 4 leg bones, unless of course you are going for anatomically accurate.
Step 2: Shaping the skeleton bones
Then use your fingers to spread apart the ends of the cylinders in order to make the ends of the bones.
Use a piece of tape to hold down the center of the end of the bone, and spread apart the plastic till you get the right shape. You can always add more tape till it stays the right shape.
