In order to get the girls' school papers and art in order I bought three plastic bins (Lowes $3.99) two for prechool (one for each) and one for Layla's Kindergarten "stuff". I printed out a label with their name and the years of "stuff" in the box as well as their class photos from that year(s). I did a side by side of Layla's preschool years and will do the same once Hadley has another class photo next year.
I love having a designated place to put everything and no longer feel the need to toss something because I don't have room for it. I'm planning to buy a new bin at the beginning of each school year from now until Hadley's senior year in 2029!!
Oh and here is how the craft closet is looking at the moment - not great but much better! I'll post more on this once I have figured out exactly how to make this space work.
