I love them, and often look at them all as I'm going up the stairs, but there are a few that I love, that didn't fit on the line, so I've made a little Polaroid Photo Holder for them - with Harry Potter background.
Picture Frame - sourced from a car boot sale for £2!
Double Sided tape
Twine / Jute
Harry Potter Scrapbook Paper
Take the backing and glass off the frame and run the twine across the in any pattern form you like.
And that's it!
Just add small pegs which can be purchased from any craft / stationery store and photos. But who's to say it has to be photos? You can add earrings, keyrings, keepsakes... maybe even a time-turner...
