Organised chaos

This week's SBQ:
Do you have an organisational system for your patterns? If so, how do you organise them? If not, have you considered organising them?

I keep my charts in plastic box files and sort them by designer. For the miscellaneous ones I tend to organise them by theme, eg bunnies, seasons. I have small box files for smaller charts, eg Lizzie*Kate flip its. Magazines are stacked up in chronological order by title. I have a small bookcase with knitting and sewing books on the bottom shelf, magazines on the middle shelf and box files containing patterns on the top shelf.
