art in the garden :: mixed media

i am loving the color-blocking trend right now... which has inspired my 'art in the garden' donation for the annual fundraiser at lincoln memorial garden.  aren't they fun?  please pardon the paper wrinkles - the images are printed on a linen paper, which is so thin the paint distorted it a bit.  i have them flattening in a heavy book as you read this.  i need to figure out how to frame them...  my original thought was to use an old window, but i am having a difficult time finding a 4-pane window.  so many are six-pane or more.  any thoughts?
