Cupboard Elves

I love my cupboards! They are solid pine with movable shelves. However, I think I have a shelf elf! The shelves are adjustable with little holes up the inside so that you can change the height of the shelf. Just last week the under counter cupboard came apart. The little plastic gizmo that fits in the hole had come loose and down came the shelf. Thankfully, I had a high pot below and that held everything up until I fixed it. I do try to check every so often and renewed my efforts. Today I saw, as I emptied the dishwasher, that the gizmo was missing in the second shelf that holds glasses. I found it, replaced it, and all is good. Tiny problem, good solution, I do still love my kitchen cupboards! Now if I could just get that elf to stop taking the gizmo out!
