Oh you can definitely make buttons from polymer clay, and you can make them just about any shape or style (including skulls)
First, "polymer" clay is an oil-based clay (not water-based like air dry clay or mud based like earthen clay), which is "cured" by baking in an ordinary oven (or toaster oven), generally for 20-30 min at 265-275 degrees F (130-135 C). It never "dries out."
(btw, "modeling" clay like kids use is also an oil-based clay but different because it has wax added to it and will just melt if you try to bake it.)
The main polymer clay brands you're likely to run across in craft stores in the U.S. and Canada (or online) are:
(bulk boxed white or terra cotta Sculpey
, boxed flesh-colored SuperSculpey
, and 2 oz bars of colored Sculpey III
) (manufactured by Eberhard Faber)
(also manufactured by the Polyform Co....called "Premo! Sculpey" only by them, or in print
(newest polymer clay) (manufactured by Van Aken, but they make several clays)
...and occasionally Cernit
The main thing that's important to point out about brands is that the Sculpeys are weaker
than the others after baking (bulk plain Sculpey is the weakest...SuperSculpey and small bars of Sculpey III are stronger, but still weaker than other brands).
. . . How strong or brittle a polymer clay is can affect how well it works as a button
becuase the final clay object will receive stress. So if you make thick
skull buttons with no parts that are projecting or thin
, Sculpey will be fine... otherwise go with one of the others.
Another thing you might want to know is that polymer clay buttons can generally be washed and dried right on the clothing
(don't dry clean them though).
If you decide to try skull buttons, here are a few pages from my polymer clay "encyclopedia" website that will help:

(...look under "Non-USA Suppliers
......or get in touch with one of these Canadian polymer groups
and ask them good places to buy polymer clay:
(Canadian Polymer Clay Friends/Amies)
Quebec: The Montreal Polymer Clay Guild
, now in its third year, meets once a month at the Visual Arts Centre, usually on the first Monday of the month but sometimes Tuesday instead. Contact: Lynda Gould, tel. 514-931-8667, e-mail <firstname.lastname@example.org
Ontario: The Southern Ontario Polymer Clay Guild
is claying together monthly, usually in Mississauga. Come clay with us. Tutorials, Show and Tell, swaps and more are features of our meetings. Everyone is welcome. Contact Marg Scott at email@example.com
HTH, and have fun!
