I realize that giant bows on babies and kids are seen by some (maybe most) as, well ... incredibly tacky. However, I am of the opinion that huge bows are so over the top, they become precious.
I ordered some cheap silk flowers on ebay and a few crocheted headbands and caps. I took apart the silk flower (removed the stem and plastic pieces), hot glued the flower back together, added a gem, and attached it to an alligator clip. Voila! Giant adornment :)
I made flower clippies out of buttons for those days Kate and Baby Garlando want a more understated look!
