I am making a keyhole scarf in which I bound off the middle stitches, then cast the stitches back on on the next row. I wanted the cast on stitches to be sturdy so I doubled the yarn for the cast on stitches. I thought at first that doubling the yarn would make the top of the opening too wide, but it didn’t. It did reinforce the opening, however, & I am pleased I tried this. Maybe this is standard procedure, but I don’t remember seeing this hint before. I thought someone else might find this trick
