Just wanted to show everyone my new thread shelves. They were very inexpensive, $5.49 per shelf plus about 50 cents for the dowels to hold the bobbins. Each shelf holds 16 cones across, two deep. I added tiny dowels in front of each cone to hold the extra bobbins. I could, and may, put the shelves a little closer together and add a 6th shelf. I painted them red to match my new painted stairs. So far I love them.. I had the cone storage racks but always had to be very careful taking the cones off so I wouldn't knock off other cones.
