I had a dickens of a time, trying to find a frame I liked that would fit 4 pictures horziontally. I could find them w/ a mix of horizontal and vertical and I could find frames w/ 3 spots, but not 4.
So I gave up and got dollar store frames, painted them black, and put them in there. Mostly successful.
Buffy does refer to them as 'the finches'; she seemed unimpressed by me trying to explain the bill shapes and the food/evolution standpoint :-P
