S.B.
I accidentally found them at Hobby Lobby the other day! We were looking at the jewelry making section and I found them near the tote bags, with a bunch of stuff for babies, like little hats and bibs.
I have been making cute hairbows with instructions from this site: http://girlythingsbows.com/index.html The button flower clippie is my favorite.
You could go to any fabric/craft store and haunt the remnants areas, where they have fabric that was left over. I have found cute things in there to make little purses and bow holders and stuff for my daughter. You could use random bits to line their trunk, I would probably tack them down with thumbtacks, the flat kind. You could also decorate with ribbons and stuff.
