Maybe that stuff called goo be gone, I have seen it at the drugstore I think. For future reference next time try un-do to take the whole label off. It really works wonders and gets it off with no residue left behind. You can get it at Walmart I think drugstores and maybe even Joanne's.

Here is a link that might be useful: un-do

I use a blow dryer to warm and soften the glue before trying to peel labels or price stickers. It works really well.
You might give it a try on that gluey spot. You'll probably be able to get it off with your fingernails after it is warmed.
Good luck.

Thank you, thank you! Since I didn't want to head out to Walmart tonight, I decided to try the blowdryer. It worked perfectly! Now I can start on my piece tomorrow.

You're welcome :) Glad it worked.
