mrss - you are the reference guru!
I have them and use them on my GM picotin. The picotin is potiron, and the pom-poms are great because they seem to have every colour. I think it really looks great on that bag - but I don't wear it on any of my others (everything else is much more classically neutral - VN, barenia natural, marron glace - and I don't really think it goes... actually, for the VN/barenia, I got a horse hair charm!).
