My mum was going to throw out all her old slides. And there were a lot of them.
I once saw a DIY project were someone made a curtain from old slides, and it looked spectacular, so I thought I needed to do something with Mum's stash.
I used PVA glue to attach (some of) them to two canvases. I then attached a string of fairy lights behind.
At night time the display is quite pretty.
