I added small pen dots to the corners of each piece and then used a very small drill to drill the holes.
I then took two pieces of elastic and started threading them through the holes - initially just as two lines until I discovered crossing over looked quite good!
As I've got quite wide wrists, I figured I needed 4 square pieces to fit. I kept a pair of scissors handy as whenever the ends of the elastic frayed, I trimmed them a bit.
I couldn't not let our eight year old daughter have a play too - she decided on a whole new style and without any help, did the following. All I need to do is find some more of the puzzle pieces to make more! Does anyone know the name of these?
