Diagonal Box Stitch Afghan In Progress

I am making this diagonal box stitch blanket for my son's best friend's baby boy.

I used 3 (5 oz) Bernat Softee Baby Denim Marl and an "E" hook. It measures 34" x 34".

I'm still trying to decide on a border.

Here is a pic of the blanket I am working on. Thanks to the wonderful people at Crochetville for helping me with border ideas.

I have worked up a border of one row of single, one row of half double, and one row of reverse single.
