Thanks to ALL for your numerous and wonderful ideas about what to put in the Elvis bag for my retiring friend.
Pat, from 501 Quilt Blocks (http://www.501quiltblocks.com/) is our winner. Pat came up with the power bar suggestion, and that triggered idea for me: I decided to put in things that could be used in a variety of ways.
For instance, the fat quarters would appeal to any quilter, but the fabric theme would appeal to a future preschool teacher. The power bars could be used for Amy's biking, traveling, power quilting or to help her keep up with her preschool students. The Crayola washable markers could be used in a preschool setting or by a quilter.
Other ideas I LOVED, but could not locate or make in time included a blue suede shoe key chain, Elvis socks and a blue suede shoes quilted postcard. Thanks again to all for the great ideas. This turned out to be a lot of fun! :)
