I've finally taken the plunge and opened an account on RedBubble so that I (and any other deluded people who feel so inclined ...) can buy prints and greeting cards of my work

There are only half-a-dozen items there at the moment but if anyone has a particular fancy for a specific piece, let me know & I'll do my best to make it available.
Cards & Prints at my RedBubble GalleryI didn't realise it was going to be quite such a long slog to do the necessary re-rendering and the problem with UF pieces in particular is that when you render them in humongous sizes, you might see tiny flaws that weren't evident in the original render ... so back to the drawing board for those.
Just saw you'd been featured: congratulations!!
I've come up against the problem of dealing with jagged lines etc. that I normally don't have to deal with.
