I finally sewed the buttons on Sabrina's bibs. They are bibs o' love (rav link) from Mason Dixon Knitting. I just love this pattern, it is so versatile; I easily modified it to a log cabin bib.
Now they can join the rotation with cmv's turkey bib
mlm's octopus bib
and Melinda's quilted bib
Here's a before picture, you can hardly see Sabrina or the bib once she has finished eating.
