The author of this pattern is Lorna McMahon and she sells on Etsy. She has several really nice patterns. We were lucky enough to have her as a speaker at our Guild, a couple of months ago, and she also came back to teach a workshop. She is a very very talented quilter.

I have the giraffe pattern and all fabric necessary, sitting on my cutting table. I just have to expand the pattern to include another baby. You did a really nice job if your quilt and your coworker is a very lucky person.
