Remember when I said I wasn't cut out for blogging? Apparently I'm also not cut out for mindless knitting. Possibly as a result of seeing my aunt's actually amazing quilts, or possibly as a result of discussing it with a friend, I finally decided to finish the border and sew it on. It took me all of about five days (probably less). But at least it's done. And all of my ends are sewn in too.
In my defense, we've been using the blanket since I finished sewing all of the squares together, just with loose strands hanging off the back and lacking a border.
