The Booga bag is so cute! and I **L O V E** noro yarn.
About the rubber stuff on the bottom ofslippers... i read somewhere that you could use puffy paint/fabric paint on the bottoms of slippers to make a non-slip sole. After the slippers are dry, just squeeze the paint right rom the bottle ointo the bottoms.... you can do swirlies, names, ... customize for each person in the family. I suppose you could put it on the tops to, for decoration. I'm pretty sure that stuff is washable, but I've never tried this technique.
