/diy/ - Do It Yourself

I snagged a sweet deal on a new vanity/top/Delta faucet, like $30 all together, and put it in. It's my first time doing anything plumbing, so I think I overdid the putty under the drain, as it now sits proud, and water doesn't drain around the edge. Is there an easy fix, or should I just remove it and redo that bit?
