After instructions for picking up border:
Though the edge could be worked in the round, it is worked flat to keep an even garter gauge. Turn work to begin the next row.
Border Row: *K1, KFB, K to 1 st before next marker, KFB, K1, SM; repeat from * to end of row: 8 sts increased, 358 sts overall.
Next row: Loosely BO all sts, using larger needles if necessary. Be sure that the bind off matches the stretch of the rest of the fabric.
