Testing out the search on Philofaxy the other day I came across some posts from 2013 (11 years ago) this followed our Skype chat last weekend.
During the Skype chat Jess was telling us about her first Filofax organisers. Her first one was a Cobalt Blue Calipso Compact
Jess later moved on to the Osterley model in two of the colours, she was showing us one of her Osterleys, which she uses for all her spare inserts and future months diary inserts.
Her is Jess with her Osterley at the Washington DC meet up that I attended back in June 2015.
This search https://philofaxy.blogspot.com/search/label/Calipso bought up two great posts! Take a read of the posts from Susan and Zoe
I'm sure we all remember our 'First Filofax/Organiser' What was yours?
