Decreasing st at neck edge
My directions say, working both sides at once with separate balls of yarn, dec 1 st at each neck edge every RS row 3 times. I have decreased my stitch at the beginning of my row, do I also decrease a stitch on the left side of my neck edge? Also, my rows all have a selvedge stitch, do I slip stitch the first stitch on my left side? Hopefully I have successfully asked what I need to know.
