One Down One to Go... and a great use for plastic bags!

I have been working on a commission for a lady that has mini donkeys. They are so cute! I think they have the sweetest faces.
The past couple of weeks I have been dog sitting, first for my dad and his australian shepherd, Abby, and then for my daughter and her two chihuahuas, Bonita and Bella. I took my art supplies so I could work. But it's not the same as working at home with all your artsy stuff at your fingertips.
I am working on a second commission of a very large painting of Koi (36 x 48). This one is not going to be so realistic as the donkeys. I am using a bit of collage in it. Anyhoo, not being home with my 'stuff', I found there were some things I needed but didn't have. Part of my collage technique is to have very accurate shapes to draw on the paper I want to collage. For instance,
One of the koi is going to be collaged on. Normally I take tracing paper and trace the koi shape off the painting, then I use graphite paper and retrace the shape onto the patterned paper I want to use. Well.... guess what I DIDN'T have with me? Tracing paper!
So being the artist that I am... I thought and thought about what I could use for a substitute. My first experiment was to take a piece of type paper and totally soak it, so it was somewhat transparent, stick it on the painting and trace my fish. Then I got the blow dryer out and dried it. It worked good enough, but was a long process with the wetting the paper and drying it for this impatient artist. So then I had this really good idea! I got a white plastic bag (this one happened to be from Wallymart) and cut it in half and used the blank side like tracing paper. It worked just perfect and was more transparent than the wet typing paper. Hooray! I didn't have to go home to get the tracing paper. (Yes I am sure you are thinking why didn't I just run to the store, but like most artists and supplies, I have a hoard of tracing paper and couldn't bring myself to buy more!)
