It would make a cute center piece for a baby "changing pad". I usually make them about 22" x 24", and quilt around the design. Then I put a binding around the outside, and embroider the baby's name somewhere, either on the quilted top, or the plain back or the edging, whichever shows up best.
These are so handy -- someone made one for me when I had my first baby (she is now 33), and I have been gifting them ever since...
