That looks really great! And I'm sure your Dad just loves
it. The flowers are well done and design elements nice too... love the fence and the mini-scene.
Great to hear how well your Dad is doing!! (I had a friend who's husband went through something similar a few years ago... all is well now though
Did you know that the polymer clay community also makes something called Bottles of Hope
(or Bottles of Caring), for cancer patients in particular?
It got started when one polymer clayer was getting chemo for breast cancer and noticed all the little empty bottles of heparin (used to push the chemo) around ... she asked for some to try "covering" with polymer clay and discovered they're fine in the low heat needed for curing polymer clay ("medical" plastics are usually fine) then began making them for the other patients she sat with during those times. Pretty soon her whole polymer clay guild was making loads of them for other patients, and the idea spread like wildfire.
You can read more about BOH and see lots of examples of the ones that have been made since then, if you're interested, starting with this page at my site (I'll also include another page that shows some of the ones I've made; mine are mostly just "covered" and sometimes embellished a bit, but many people have made all kinds of objects/figures/other things with their bottles too):http://www.glassattic.com/polymer/BOH.htmhttp://www.glassattic.com/imagesCANES_COV/cov-BOH/BOH.htm
Btw, if you're interested in even more types of polymer clay sculpted flowers and leaves, check out this page:http://www.glassattic.com/polymer/sculpture.htm
(...click on the category Flowers & Leaves
And here are a few more examples of "flowers" in vases/etc, but in miniature
... they were made by members of my pc guild for an "exploration" theme we had of flowers in containers
I haven't done anything with clay since pottery in high school, lol, but I happened past the Sculpey aisle . . .
If you're new to polymer clay, notice that in that "Sculpey aisle" there are other brands
of polymer clay too. Sculpey III, boxed SuperSculpey-flesh, and boxed original Sculpey are the weakest of all the polymer clays in any places where they're thin or project out so those areas can easily break off or chip if stressed or hit, etc. You made your flowers fairly thick (probably since you're used to dealing with earth clay) which should help a little, and they probably won't get stressed since they're only for display, but next time you might want to try one of the other brands especially when you'll have thin or projecting things (stronger clays won't break even when very thin --in fact, they'll only bend if thin enough).
If you want to read more about the characteristics and advantages/disadvantages of the various brands and lines of polymer clay, check out these previous posts (which both include a link to the page at my site that discuses them all in much more detail):http://www.craftster.org/forum/index.php?topic=254010.msg2836103#msg2836103http://www.craftster.org/forum/index.php?topic=73664.msg2304571#msg2304571
Definitely let us see other stuff you make!
