Hey GG - I know the way I explained it before was confusing
My husband frequently tells me to use my words,
but doesn't tell me how
So when you did your ruffled bag, it's like that. I worked the bottommost portion of the back panel, ending on a RS row, put it on a spare needle, then I began working the following section, knitted approximately 5 rows, ending on a RS row, then purled both sections together, wrong sides up, with the bottom layer (the longer one) on top of the layer (the shorter one) with the working yarn. Then using my working yarn, I *purl together a stitch from the first layer together with a stitch from the second layer*, repeating from *to*.
