I did some research. (I looked at a lot of baubles on a lot of trees in some lovely shops.) I decided that I would go sophisticated. Paint the baubles with a lovely deep rich green, maybe add some gold mica, wrap ribbon around and top each one with a lovely wired ribbon rosette. Sounds terrific doesn't it? Well of course it does. And of course, it didn't happen!
I found myself painting dictionary pages with a green squirty paint (from the stash of no-longer-sprays that I specialise in owning). Then I ripped the pages up and used PVA to adhere them to the baubles. Takes a bit of patience coz of drying time (yawn), and for some, it's a bit messy. Ask me how I know. On the plus side, once it's dry, PVA is easy and fun to peel off your hands!
