And then I decided what to do.
There will be the peaks..tips..er. what is the name of a top angle?... of the hexagons but it will be ok as I am going to make my own cushion pad which will just be square.
Ok, so I didn't explain myself very well, did I?
Here are some more photos which I hope will help and if they don't then you will just have to trust me.
here is a link to a blog where the person explains it much better.
She is making a quilt and I am making a stuffable cushion so obviously I need mine open.
Hope that helps.
