HELP: Sl3Pwyib

HELP HELP HELP!!!

What does it mean when it says Sl3Pwyib or Sl3Pwyif. I know how to do a slip stitch purlwise, but sl3p??? Meaning I just slip 3 stitches purlwise? And what does it means for yarn in back or yarn in front???

Is it like doing cables???

Thank you so much for your help!!!

PS: this is a pattern for a wrap around shrug that’s worked sideways in one piece.

I think you’ve got it already!

It’s just, hold the working yarn in front or in back of the work. Then, slip 3 stitches purlwise. Likely those stitches are making some sort of pattern - like in a ballband dishcloth, the slipped stitches from the “mortor” lines between the contrast color “bricks”.

Usually it works out that the ‘yarn in back’ or ‘yarn in front’ ends up with a strand on the wrong side.
