All very true, but getting the shell to stay put and not roll over necessitated use of unsightly wads of Sculpey, the polymer clay, all round the base of the shell. (I tried less at first and spilled water over an envelope all ready to send to the accountant. I've been that way today - brainless!) I set everything up on a small mirrored square, and it has stayed successfully in place.

I think it was worse on this end than anywhere else - some of you may know differently! At any rate, the blog is reconfigured at last, and it has subscription widgets and 16 pt text. Maybe the text size is a little too large now? I'd really appreciate feedback!
