All the windows in our new home have these little keys. Well dont you always find they go missing....here is my idea.
Take an old key, spray with white paint then scratch it a bit to make it look vintagey (if that's a word) then hot glue some little flowers on and tie around the widndow key, hey presto,you have a lovely hanging decoration when the key is inserted.
This could be used also on vintage cards.
Shabby Chic!! Hugs Vee xx
