Mono Monday - Appendage

I had no idea what to blip when I read what the theme for today was.  So I went back to basics and looked up the dictionary definition.  One of the definitions was 'a part that is joined to something larger'  Eureka! I knew exactly what I could do.
The keyring, which is an appendage to my handbag.  It keeps my keys safe and tucks neatly inside the bag so that the keys are not on show.

Many thanks to Laurie54 for hosting this week
