I have flat bed knitting machines and have always loved the look of plating. I wanted to do it on my circular knitting machines Addi King & Sentro so I did.
I think the natural roll of the purl side on to the knit side would make a nifty looking hat brim. You can also play around with striping (I talk about it in the video towards the end). I thought you might enjoy seeing how to do it. hope you will try this and share with others.
