Panels can be very fun to work with. The one thing I have learned is to have "spacer" fabrics to make up for block sizes in the borders around the panel. Some panels don't end up the size you want if you just add equally around the panel. Spacer fabrics, like what feline fanatic has done with the fish fabrics borders, make it easier to incorporate blocks. I don't know if hers are the same all the way around but it the top and bottoms panels were an inch thinner, no one would notice.
