I'm a pushover for pretty patterned paper. However, it's so simple to create your own custom versions that I thought I would share some more tips and ideas in this post and in the coming days. Please see Background Check (Part I) for other custom background paper ideas. All photos may be clicked for a closer peek.
A background stamp should be flipped on it's "back," rubber side up. Think of a turtle. Next, ink it up thoroughly.
Place card stock directly onto inked stamp, carefully aligning it. If you move it on the stamp, the image will smear. Lay a piece of scratch paper on top of the card stock. 
TIP: For uniform inking, use a Brayer (Stampin' Up! Spring/Summer Collection, p. 185) to roll over the entire stamp, making sure to keep one hand holding the paper and card stock steady on the background stamp.
TIP: I always use a larger piece of card stock than I need and do my cutting later in case there are any imperfections (which is exactly what happened to me on the right hand side as I was trying to hold everything in place and take the photo at the same time–always rather humorous for my family to witness this balancing act).
