I think Container Store is my favorite store to buy gift wrap. It is a little pricey, but it is truly beautiful. They have matching bows and other accessories also.
HGTV shows that recycled brown Kraft paper is a great anytime gift wrap. Tie with twine and embellish.

I usually buy most of my wrapping paper from Sally Foster. It is a company that usually sells through the schools for fundraisers. I became addicted to Sally Foster wrap a few years ago, when a co-worker was pimping, I mean selling it for their child's school. I love the paper, because it is thick, cuts easy, and is usually reversible.
