Love the edging.. should be able to figure it out... looks like it is just Dc, ch 1 around, then sc evenly, then dc shell in some stitch.
stunning edge on crochet blanket - Links to Etsy. No pattern, but looks like a double crochet shell stitch with a picot in between each dc? Looks easy to reverse engineer.
