BEWARE ! ! !
There´s a mistake in the assembly. On the first page of the assembly you have to sew HST units together in pairs. When you look at the picture of the HST´s and how to sew them to the corner squares A you will find out the left HST´s are wrong, they have to be mirrored to get them right. I hope this makes sense, look at the picture of the four HST´s with the diamond unit and imagine this sewn to the corner square. It won´t fit!
I´m sick of all the mistakes in these patterns and considering to stop making this ´thing´.
