I thought maybe I would wait til I had done a little more, but oh well.
I've transferred two drawings to canvases and outlined them in a thin brown paint. It took longer for the primer to dry than I expected, which is why I haven't transferred the third, although I can now, I just haven't. But, the fourth drawing, I'm not sure I like, so I may just put it on hold. I may change the image altogether. So this weekend I intend to finish transferring the drawings and do the imprimatura.
