There was one bit I had forgotten and a friend reminded me, that it is important to wear sunglasses at the beach!
And then last Saturday I woke up in the morning with this idea. Don't ask where they are coming from!
I made the mirror from an oval piece of glass I had (probably from a picture frame) and some self-adhesive mirror-foil. I love when I just can go to my stash and not have to wait for the craft shop to open!
