This pattern is very similar to many simple shawl patterns ,therefore can handle different gauges of knitting as long as you are happy with the size of the neck.Which is already on the generous side using 4.50mm DK/8ply.
This pattern is designed for handspinner yarn suggestions areonly for ravelry’s benefit .Handspun yarn should make a light air fabric where mill spun Yarn will produc3 a denser heavier fabric.
