These are both squares from the book ‘Beyond the granny square’ by Edie Eckman. I have the book for a few months actually, but finally tried out a pattern. At first sight it seems quite complicated, but in practice they were quite easy to make.
This is motiv 105 on page 148.
I added a few extra rows, because otherwise the square would be too small for SIBOL-blankets.
And this is motiv 109 on page 152.
I like both squares a lot actually. Planning on another project I am afraid ...
