Crochet border Picot stitch (how to make a square edge round) To start slip stitch to first chain after your first treble round, Ch3 then make one Picot stitch. To do this insert your hook into the first chain of 3 in the back loop, then dc 3 into the next 3 stitches from the previous row, ch3 again and make another Picot. I have dc 3 in between each picot stitch as I think it gives it the space and balance it needs for this size blanket. R epeat until you have completed all four sides, ss to finish, sew in ends.
