Glass, prints and frames
Go to Michaels and buy their 18 x 24 Home Collection frame. Buy an 18 x 24 mat with an opening of 12 x 18 inches or for a "faux" double mat look, increase the window size so that there is an additional 1/4 or 1/2 inch margin around the actual image. If you buy the frame at 40-50% off, which you can do quite frquently, total cost will be under $50. The end result is quite pleasing and looks like a professional framing.
