it is beautiful- and i agree you should add side borders to make it a *usable* size...as a wall hanging it would have very limited (customer appeal) if it is to be used as some sort of fund raising for relay-
i've made a number of quilts over the past 10 years for relay for life activities- and the ones that are the most popular are twin-to full sized (value wise) queens are popular but it seems like the best (bang for the buck) is with a bit smaller than that.
