I keep mine stacked vertically in a plastic bin, about 7 inch wide by about 5 inch tall and quite long. sorted by size - lots of my stickers are assorted colors, so sorting by color doesn't make sense. But size does work for me - if I have space for a large title, I start with the back of the bin) If I want to fit a long title, I start flipping through them from the front. Many times I'll find the perfect size and then decide which color I'll use from the ones I have.
