I am a Filofax fanatic, and added a new personal sized Original in patent purple to my collection. I worry it would take a beating in my handbag, so I just had to knit a cosy sleeve for this lovely planner.

A knitted cosy project to use up your left over sock or fingering weight yarn.

This pattern is sized for the Filofax personal planner. It can be easily adapted and customised for your favourite ringed binder.
