That's when these holders were born. Hidden away on the inside of the cupboard door they are easily accessible and removable if we need them to be.
1 inch pvc pipe
pvc pipe end caps (one for each holder)
vinyl or stickers
pvc pipe cutter
drill (drill press is even better)
Cut pipe into 4.25 inch sections.
Drill a hole about 1/2 inch from the end, making sure it's on the "back side" where any printing is.
Wash the pipes. Cut vinyl initials (or use stickers) to label each holder. I cut mine to be 1 inch tall. Add end caps (they don't need to be glued on, and then you can disassemble them later and wash them out as needed)
Install command hooks on the inside of the cabinet door. Our vanity is small, so more may fit in your doors if you need them. Let them set for 1 hour before hanging holders and toothbrushes.
Now hopefully you won't ever have toothbrushes go missing in the garbage cans!
