I need to ask... linky party

How in the world do you organize your TpT units after you have purchased and prep them?! I need some direction here. I'm a big fan of putting activities into gallon size baggies & then I just put them in my themed boxes, but I don't know if I'm content with that.

How do you organize your larger units so that everything stays together? Like the recording sheets along with the activities? Please share all of your ideas and suggestions, and post links to ideas if you have them by joining the linky party below!

P.S.: I didn't realize The Lesson Plan Diva posted a very similar question on Monday! (Um, hello, catch up on my google reader..) I'm headed her way to check out more ideas too!
