Good tip MM,
HB, I know you prefer oils and watercolors but another cool idea depending on the size of the picture/s you want, take your camera and photograph things in and outside your home from odd angles. have them enlarged to the sizes you want, frame them and hang them up in groupings. it also adds a personal touch and is quite the conversation piece when friends come over and ask what these are?
Just two more cents, that's four so far
