Target has a lot of nice ones for good prices. They have glass pulls and then nickel (with a little colorful acrylic accent)that would look pretty. If you only want knobs you can always use a plate to cover the old holes.

Wow - who knew Target?!! I like those pulls, but do you think having two on each drawer would be "too much"?

No. I think it would look perfect but that's my personal taste. I like sparkly girly things!
I bought my kitchen knobs (heavy solid brass in Venetian bronze) for just a couple of dollars when they cost over $10 somewhere else.

I think if you get the clear ones it will look whimsical. Just right for a girl's room. Colored ones might be too much.

A really light color maybe...
