I just love this Starburst RIM template it gives that extra interest on your square forms. The texture in this picture is my Whirley Gig pin and I used our 3 deep 8 inch Square Deep Dish form with our signature finger holes for easy removal from the clay

You can create so much swoop on the sides also for added interest.
