on the drawing board: double teamed

I hardly ever work on more than one piece at a time.  Even when I do pieces that are part of a series, I may have the general idea of what I plan to do for each one, but that is about as far as it goes.  They don't even get to my refined sketch, which is what comes before I get out the pastel paper.   So it will be interesting for me to see how these two progress.  I think one of the reasons I've avoided doing more than one at a time is that I'm afraid I may lose interest in one if I have something else to do.  My head might be in a completely different place by the time I can get back to it and I'll scrap it and come up with something else.
