I'm rather fond of this one. It looks like a single coral sending out its egg into the ocean. It's a circle of SIS with inward spikes, on a purple frit background. I'm thinking it should be possible to make a group of spawning corals, though they might well lose their circular shape during implosion.
Two more in pink, a flower and a spiral, both implosions too. They are both quite low in the marble, the spiral most, which makes it hard to see properly, even in person.
I'm afraid I still need to work on my roundness. Apparently I don't pay enough attention to the roundness, while I do remove chillmarks carefully. I probably should punty several more times than I do, in fact, I probably should make myself a very simple marble and punty it over and over just to practice.
I still worry about dropping the marble, and I definately do not master any kind of cold connection yet. I make my hot connections real skinny, so there is only a little bit to melt flush in the end, but of course this makes it very easy to get the punty too hot and droopy while working on the marble.
Well, there is always Practise, Practise, Practise :)
