I added one border to each of the squares. Connect yarn in corner, (ch 3, 2dc, ch, 2 dc in same stitch), *ch 1, sk next hdc, sc in next stitch*. Repeat from ** along each side. (2 dc, ch, 2dc) in each corner. NOTE: My corners didn't match up so first and third corners were instructions above, second and fourth corners were opposite *sc in first hdc, ch 1, skip next hdc*.
I tried a couple different ways to connect the blocks, but settled on joining them with a simple slip stitch.
For the border: One row of sc, one row of dc, and one row of sc making three in each corner of each row. Last row was interlocking chains using two colors. The directions for the interlocking chains can be found here. I only used the last part of these instructions that pertained directly to the interlocking stitch. I love the frilly edge it made.
Of course, Ebony approves!
Oh, and the pretty little crochet hook came from a wonderful little Etsy Shop called Polymer Clay Shed. She does an amazing job...loving the feel and quality of my new hooks.
