HA! I wondered what a waffle shade was! Food is food
I picked mine up at Home Depot. The big sizes(front & back window) 48" x 48" were on sale. But those "type" home improvement stores, do have them at a better price than total custom. Not sure what stores your have up there. Lowe's here has them. down the aisle from the custom area. Will cut down to size. Do a few at a time?
