I had also brought some pastel pencils, some black micron pens for sketching, pencils, etc...And didn't end up doing a single sketch the entire trip. I also lost the set of pastel pencils somewhere along the way, stupidly enough. We were just so busy trying to see as much as possible, there was never really time for me to sit and sketch. I held on to those mini pieces of watercolor paper though. A few years later, taking a painting class in undergrad, I decided I wanted to learn watercolor. The school didn't have a specific class for watercolors, just "Painting I, Painiting II," etc. So the first watercolors I ever did were 4 little 2"x3" paintings of palm trees by the sea. I forgot all about them until a few days ago, dug them up and put them on display near my computer.
I then decided to do a few more little mini's just for fun. I found some old flower pics of mine (remember how much I love do draw flowers) and just have a go at it with no prep sketches, just sketch with the paint right on the paper. I even had a few scraps of paper that are ridiculously small, 3/4"x2", and I thought of course, "how cute!!"
I got the idea for these mini watercolors from my old boss at the art supply store where I used to work (where I acquired the above photographed awesome art supplies). He was a watercolorist and had done little tiny watercolor paintings in art school and sold them. They were really popular and made a bit of money doing them. Since he was also working as a framer, he took scraps of old frame and framed the tiny works he did. He even showed us one he did that he had a little light bulb in it (like one of those Christmas tree lights). What a cool idea!
