I combined a bunch of the more common tips by saving patterns in my Knitting directory on my computer and printing them out. I use the sheet protectors to hold all the pages for each pattern. I use a post-it (similar to the painter's tape tip) to show the 'next' row to knit, and maybe notes.
When everything is done, I throw a picture of the finished product in and some of the leftover yarn in case I need to ever 'patch' it.
Each goes into the binder when done.
To keep DPNs from slipping out of the row I use tiny elastics (less than 1/2") @ 500 for $1 in the health and beauty department.
In department stores' luggage sections they sell little divided drawstring bags that are great for organizing DPNs, tip protectors, stitch markers and other teensy bits.
A cuticle trimmer makes a great snip if you can't take scissors for some reason.
Thanks for sharing all these other great ideas!
