I love the Valentine card envelopes shown on Heidi Swapp's blog here. I might have to try these!
Tammy Malone shows how she made this little box to hold Reese's Peanut Butter Cups in. This would be a nice Valentine's Day gift. Click here for instructions and more photos.
Creature Comforts has some Valentine Photoshop brushes available here. Shown below are the lips set, but there are others in the link as well.
Here's a pretty heart garland that would be great for V-Day as well. From (In)Courage.
