Perhaps you have already read the great day by day coverage of Mr. Lee about a painting workshop in Aachen (if not: do it, its worth a read). These articles made me think over some things and I just felt like having to write down my thoughts WHY I always missed the opportunity to go to one of those, even if they are only one or two hours away from me.
I always look into the description of the announcements of the workshops in the big tabletop forums (perhaps I should add Brushbrothers in the future too) and especially the ones from Massive Voodoo or GeOrc always get me itchy and I'm always thinking and thinking and don't register myself in the end.
