"The edging is super simple, first a round of sc, then for round 2 I did *2 dc, chain 3, 2 dc* in every fourth sc. Row three just one more round of sc."
To whip stitch, I brought the needle under both strands of the edge stitches. Instead of turning the needle around to come back the other way, I pushed my needle through in the same direction for every stitch.
