Quilt labels

How many of you add labels to your quilts and what information do you include?
Only as of recently have I added "Handmade by Olivia 2013" on a small corner in the back of my quilt but the many other's that I've given away as gifts through the years have no labels what so ever. I saw this neat idea to easily add a little label to the back corner of your quilt and that's what I've been using on my most recent quilts.

Here's how I did some of mine this year.
First I square up one of my corners(this is after you have finished quilting but before you add your binding)

 Then I take a 5" square of fabric that matches my quilt (not necessarily the backing) and fold it diagonal. I then cut from my batting scraps a triangle that will fit inside my folded square. Next I embroider on what I want my little label to say below I simply put "Handmade by Olivia", I didn't add a date to this one because if I give as a baby quilt it would be nice for it to have the baby's birth year. Kinda not sure if I shouldn't have just put 2013 after all that is when I made it. What do you think?

 Anyway's so next I just sewed about 1/8" away from my edge just enough to tack it down, since when I add the binding I will sew ¼" all around; firmly sewing it down.

I kinda figure I could hand sew a date if I wanted to add the year. What do you think? What kinds of information do you include in a quilt label? How important do you think labels are?
