Thanks for all the great ideas! I will definitely check out the Crayola box (although I think I want larger than 8 1/2 x 11 size) and the Autograph box.
I plan to use the box to trace applique pattern pieces. Can't use the large living room window anymore (furniture in front of it...I know dumb place to put furniture...it is a deacon's bench), and using the glass in the storm door may work in summer, but brrrrr....too cold at this time of year.
Thanks again for the ideas. Will have DH look at them and if he doesn't "buy" me a box, maybe he'll cobble one together for me!
