Andrea Speaks! Portuguese Yarnovers
I am very pleased to say that the first comment (it’s attached to the Knit for Your Brains – Really! post) my young blog has earned comes from Andrea Wong herself, author of the DVD Learn How to Knit Portuguese Style, with which I learned to knit that style, one of the two I favor.
I wrote to Andrea with some questions to clarify yarnovers in her style and she kindly replied as follows:

Andrea Wong created the Portuguese Knitting DVD. Visit her site to order.
“Purl- YO-purl: When you finish the first purl you have the yarn below right hand needle. Use your left thumb and flick the yarn counterclockwise around needle and purl next stitch.”
There you go. It was easier than I thought. I was deliberately wrapping the yarn around the needle but it seems yarnovers in PK are almost automatic.
By the way, you will get a k-yo-p yarnover if you don’t move the yarn under the needle before doing the pearl stitch. I haven’t tried yet, but I betcha a p-yo-k yarnover is done by not putting the yarn on top of the left needle before doing the knit stitch.
Thanks Andrea!
