For now, this is how I arrange and label them.
Some bookmark collectors I have trade BMs with label their trades, especially the non-English ones. Sometimes I asked them to put labels what they are about or, at least, a general description. It shouldn’t be something too much to ask, right? We’d want our trade partners to appreciate our BMs more by somehow having an idea what the scripts on the bookmarks say. So, I keep the labels my exchange partners put in them… just like this.
How about you? How do you arrange your bookmarks?
