All you will need is several jars and lids. I like odd numbers so always use 3. Mine cost £0.75 pence in Wilkinson and £0.99 pence for the screws.
Place the jar lid on your mat and pierce with the bradle so the whole goes right through. Check that the hole is big enough for the screw to fit.
I have then tied wooden hearts with writing on and stored, buttons, ribbon and bits 'n' bobs.
Used here in my bathroom to store ear buds, cotton wool and guest soaps.
Very effective and useful........and very cheap and easy :)
