With every baby shower that rolls around, these are one of my most favorite and simple gifts to make. Its just that one gift that they are sure to not get a lot of, and even if they do, the more the merrier.
I use a great and easy pattern I got off of a fabulous website I follow. It is the purl bee, http://www.purlbee.com/fabric-beach-balls/
I printed off her tutorial patterns and laminated them. That's how often I use them. Sometimes I even put in a little bell inside for a touch of a noise maker.
