Felt, ruler, scissors, hot glue
Glue the felt pieces together. First place two glue strips about 1/3 apart across the front of the felt, then glue 3 glue strips on the edges and in the middle...repeat till you have glued all the felt together.
You can make this as big or small as you would like. We chose a smaller organizer for a small sock drawer.
This is the finished design.
