Organizing our learning materials by theme

I've been fretting over getting my learning materials organized.  I happened upon these sterlite file boxes at walmart for $6.97 each.  Had my label maker ready and started pulling out the boxes and boxes I had filled with learning materials.  I was using large manilla envelopes (with huge labels) and had things in numerous boxes.  took a while to get it all organized but, OH SO WORTH IT! Our bookshelves are getting crowded so I was able to put just a few books into the file boxes to save space on the book shelves. Got everything from ABC BUNNY to ZOO!!!
