Over the years, I've bought 3-4 dozen flies from a famous shop located in Manchester, VT to use as models for flies I wanted to tie. I have also been given several dozen flies by friends, friendly strangers on the stream, and some wonderful FAOLers. I've saved about 6 dozen of my old flies which took some memorable fish or were retired due to old age. I guess that's a fly collection but I just keep them in a well moth-proofed drawer. 8T
