Easy peasy potty ideas... buy some cute duct tape... use a 5-gal bucket (old paint/laundry soap etc.) and wrap the duct tape around it...
if you are adversed to a narrow rim, Cabelas sells a seat toper. aprox. $15 give or take. or you can buy the complete set up... and decorate it if your heart desires... or sew a 'cover' top to give it that ottoman look, discreetly hiding your potty.
