It's very possible she removed the straws prior to baking, though she would run the risk of the clay pulling and warping as she did so. However, it's also highly possible she simply boiled the clay. Polymer clays, such as Super Sculpey, can be boiled in water to cook it rather than baking. It helps to prevent burned clay and tons of "moonies" from showing up. Afterwards, just pull the straws out!
However, I totally prefer using wood, especially since I bake my sculptures and I don't have to worry about the straw bending or flattening. (I really
should boil... >_<;) I tend to root around for cheap, easy to find materials, so here's a few of my suggestions for wooden armatures. Depending on the size of your project, the sizes will vastly vary:
- wooden dowels (lots of places have these rather cheap in their craft section. For example, Wal-Mart sells a pack for $1 that has a variety of sizes perfect for SD and MSD sized dollies: http://www.walmart.com/ip/Kids-Craft-Ro ... s/19613459 These are the exact ones I have and use.)
These are what I stick to, but I've also used random things like pencils without their tops, paintbrush handles, wooden cotton q-tips with cotton removed, and even the brass stand part of a baritone sax! (Though, I took the brass stand out before baking...) Really, if the size fits your scale, and it's safe to bake or boil, I say go for it. ^_~
I would also suggest carefully pulling the wooden armatures out before the sculpture fully cools and while the clay is still pliable, just so you don't have too much fuss pulling them out once hardened. It's also good to cut your sculpture apart while it's in this warm stage, too, fyi. The x-acto knife slips through the clay just like butter. *_* If you let your sculpt harden but still need to cut it apart, you can re-warm it up and it'll become pliable again. /o/ For everything else, I rely on my trusty dremel. =pets her bebe=
