I had a similar toy to this and loved playing with it and making the patterns which I think its why I bought it for my big girl.  Until now its not been a huge interest for her but she dug it out the cupboard and I couldn’t resist having a play with it too.

There are some lovely EPP patterns here but I am slightly struggling to get past the primary colours.  Also to make something of a decent size would take me centuries at my current rate so thinking about speeding it up/ modifying the process of an impatient person like me.  They also all seem to make up a hexagon or triangle.  I enjoyed working out how to make more difficult shapes repeat.
