got paint?

I have had to make some hard decisions this week.  I hope they were good decisions.  Yesterday, I went to Hobby Lobby and purchased 3 tubes of acrylic paint in hopes of finishing EIEIO by my December 5th deadline.  My stride was broken, so I don't know how I can get back into the momentum.  Painting for me, is sort of like going down the rabbit hole.  One of the first processes that I had my art students do this summer was to learn about primary colors, how to mix them into secondary colors.  They became quite good at it, and now I am faced with needing to be good at it too.  The art teacher has to walk the walk this week. 
Prior to this week, I have been using mostly recycled and donated paint.
