Hi!  Your wall looks great (love the paint colour too btw)! I fell in love with botanical prints a few years ago and had the same issue with availability and price as you did.  I managed to get some really gorgeous prints from a calendar that just happened to fit perfectly into Ikea frames complete with mattboard.  I bought 5 frames for $30 each and the calender was only about $12 - bargain!  I've had them up for about 2 years and still love them.
