PLEASE NOTE - this pattern will not be square using 3 turning ch on UK tr (US dc) rows. Please trust the instructions.

This blanket was improvised from the centre out using mostly mitred squares. It’s worked simply in squares, letting the colours create the design. There is a version that uses curves instead of mitred squares in the design.
The yarn I used is not available in the USA.

Thank you, Tammy (takdpm) for sharing your version!
