The pattern is actually an old Norwegian kind of pattern used by house wives many years ago. It was a utilitarian way to use up fabric pieces. They made pillows and other things with it.
I live in Norway and had seen many pilllows using it but didn't know how to quilt then.
Lately, I found the idea in a book called "Sew in a Row Quilts" by Karin Hellaby. She lives in the UK, but her parents were Norwegian. She calls the pattern CHOP SUEY.
It is easy, just choose your colors, cut them into strips of varying sizes then sew the strips together. After that cut the piece into squares and then cut the squares into 4 diagonally.
You can put them together in a myriad of ways. After playing with it for several days we decided to make this pattern and separate the parts with sashing.
