Attaching a button

As I was making another kitchen towel hanger, I thought to myself:  I add beads to knitting,  It shouldn't be that much more difficult to add a button while crocheting.
It turned out to be relatively easy.  All one needs to do is pull chain sts through 1 or 2 button holes:
The first image is of ch sts being pulled through the first hole.

The second after pulling ch sts through the 2nd hole.

Finally, the loop is tightened.

Crochet the rest of the row.  In the next row, sc (or dc or tr) 2 sts together - one into the ch sp just before the button and one into the ch sp just after the button.
