Granted it's the ribbon lengths (there's 3/8 in there too)... but, if you already know how to make the big ones, you should hv no problem doing it with a 3/8 : because, it's the same concept/method. The only difference between the bigger and bitty bows is the ribbon size/width & length required.
How to put it on an alligator clip: the same way as the bigger bows. Maybe this will help... Free Hair Bow Instructions and More!
