I love creating backgrounds. Almost any stamp set can be used to create a beautiful background or custom background paper. This is one of the many reasons I fell in love with stamping... and ink... and cardstock, oh my!
I've created this fun Terrific Ties card for the MFT May Creative Challenge... as it's all about backgrounds. I may even have a few tips. ;)
Another fun way to highlight a background is to pull some of it forward and add dimension. Coordinating Terrific Ties Die-namics help so much for this for this card!
