When I first started creating with polymer clay, I attempted to cover everything that would go in the oven. (Doesn't everyone?)
I covered bottles, jars, cans, pens.... and then I joined a polymer clay central swap (I think it was 1999) for covered eggs.
I attempted, with limited success, to place slices of canes on the blown out eggs and smooth them out toward one another. I'm not a swearing person under normal circumstances. However... there were several eggs that wound up with my thumb or finger breaking through the shell just as I was placing the last couple of cane slices ever so carefully... just so... @#$&*#
I did, in the end, finish the requisite number to send out. Sanded and sanded and sanded and buffed on my blue jeans.
Now, those of you who are smarter than I was then have probably already figured out that there is a much more secure method for covering eggs: cover with a thin layer of clay, making sure to pierce that "blow hole", and baking. When I read that tip, I felt like such an idiot!! Ah, well, not the first time and certainly not the last...
I did get better at it...
