Just to show off a little more (especially now that I can show off more than one photo per post ). My mother gave my eldest a big box of Prismacolor pencils for his birthday, but it was an awkward shape to carry around. He asked if I could make him something better.
There are six trays that nest together, and I got the kerf right so that they will stay together when stacked but are not too hard to pull apart. He used the pencils to color the lid.
Also, my kids alternate responsibility for setting and clearing the table and for washing the dishes, and my husband and I can never remember whose turn it is. So I fixed it.
