Joining a community blanket is a zen exercise. Do not give this task to the Type A-est person in the group; it will drive them mad. It needs to be done by a person who is experienced with and willing to participate in the Fine Art of Fudging.

FAF involves easing where necessary and relinquishing a commitment to symmetry. The border might not match up exactly at the corners. This is OK. A more Type A person will rework the border stitches so that they add up to the proper stitch count for the border

(FYI: If you are one of these people, this border calls for a multiple of 6 ch-sp; to adjust this, you probably want to add a round of sc before the rnds of ch-1 border, working sc2tog or inc sc as necessary).
