Technique tutorial: Brioche stitch
Brioche stitch is worked in rib where you alternate between working the knit stitches in one round and the purl stitches the following round. When you work the knit round, make a yarn over before the purl stitches and slip the purl stitches.
When working the purl round, on the contrary, make a yarn over before the knit stitches and slip them.
