This week I crossed off one project on my big list: Organize piano teaching supplies and music
I teach a few piano lessons each week as a little side job. I have found many great teaching aids online (worksheets, games, flashcards, etc) and I had previously stored them in a binder and a box. Well, that binder grew to three binders and a junky box, and things were out of control.
So I transferred everything to one file box. Games and worksheets can be quickly found now that they are organized by type (beginner finger numbers, rhythm, note naming, etc), and there is room at the front of the box to hold my flashcard sets and other game supplies.
This cute little box will now sit on the piano to keep pencils/pens, stickers, and dry erase markers in easy reach without rolling around the piano.
This basket sits next to the piano to corral my children current lesson materials. With three children taking lessons, their books need to be easy to reach and put away. 
In the fall I started work on organizing our music collection. The biggest issue was organizing sheet music, so I added a few labeled binders (our collection of Christmas music grows a lot every year since my husband I both end up accompanying various ensembles every season). I finished this up over the Christmas break. Now I have two shelves dedicated to music and it is all easy to find!
Phew! It feels good to cross all of that off my list!
Impressive! Good job!
