Muscle Anatomy With Sugru and a Halloween Skeleton




I've been teaching myself anatomy in order to get a better understanding of how to draw the human figure.

Here is an exercise you can do, using an inexpensive halloween skeleton from Dollar Tree, and several packs of sugru.

Incidentally, it looks like a college course (feets of clay) has taken up this approach to studying anatomy.  (I like to imagine that this instructable inspired it.)

Step 1: Materials

sugru (approx $1.50 each)      $7.50
two orange packs
one blue pack
one green pack
one black pack

one plastic halloween skeleton from the Dollar Store
4 for $1.00

Step 2: Sugru

Sugru cures relatively quickly.  Working time may be two hours at the most.  30 minutes is the recommended amount of time, but I found it could be worked longer.  So, for this reason, it may help to prepare the individual muscles in advance.  The guide drawing below gives an approximation of the amount of sugru needed for each muscle.  Assume the pieces are very flat - 1mm thick or so.

Sculpting with sugru straight out of the package is a bit like sculpting with chewing gum. Though as it starts to cure more, it becomes more like sculpey, which is good. It grabs onto itself very well so you have to not only work quickly, but once you lay something down, it is very difficult to pull it back up or manipulate it further without manipulating the layers underneath.

The great part about it is not having to bake the skeleton, as you would with sculpey. These skeletons cannot withstand even 150 degrees of temperature I found out early on in experimenting with sculpey

Step 3: Muscles of the Upper Leg

Step 4: Muscles of the Upper Leg Back View

Step 5: Muscles of the Lower Leg, Back View

Step 6: Muscles of the Torso and Upper Arm

Step 7: Muscles of the Torso Back View

Step 8: Muscles of the Forearm

Step 9: Muscles of the Forearm Back View

Step 10: Neck Muscles

Step 11: Finished


Hope you find this sort of useful as I did.

    Thank you! Yes, there's something about handling the skeleton and applying the muscles directly using different colors that really helps. Also, it's sort of hard to visualize the muscles and how they interact just by looking at illustrations.

    Very cool! I wonder if the skeleton would be strong enough to support major internal organs, too. Hmmmmm...?

    I'm sure it could be done, but its such a small skeleton, you'd have to be kind of skillful to get them all in there. If you do it, be sure and share the photos! =)
