2 Gallon ziplocks hold a LOT of fabric, the pattern, any special templates, etc. Then, I store the ziplock in a plastic storage container labeled with "WIP", "Ready to Start", TBD, whatever (I have different categories and some with deadline dates on the outside). I find the ziplock helps keep the whole project together and then keeping things sorted by other categories allows me to grab something ready to go. I hate picking up a project with anticipation only to find I'm missing a key component and can't work on it right away.
