I thought I'd share how I store my collection of projects not yet started and my thread stash, this is something from looking at a lot of websites and blogs and craft stores I know is completely up to you and what you prefer! There really isn't a wrong way as long as they are safe from the elements and for threads no cardboard with acid that over time can cause damage.
I keep the whole project in a plastic box big enough to fit the project and hoops and accessories :)
Now while stitching a project I keep my threads on the card they come on as you'll find most projects have presorted cottons. As the thread won't be on the cardboard for a long time I cut up old tissue boxes or biscuit boxes into appropriate size rectangles and write the symbol and number given to that colour by the pattern makers, you could also mark the thread brand and colour number given by the brand. This sounds complicated but it really isn't, these self made floss bobbins are cheap (FREE) they can be thrown into the recycling bin when finished.
