That’s right. Today, on my birthday, I am ironing paper grocery bags!
I think I got this idea from the old HGTV show, “Room by Room.” (with Matt and Shari, you can still find them on You Tube.)I am making photo dummies in different sizes. 
I have a photo canvas being created right now that will be 16×20″. In the meantime, I can carry my paper dummy with me to see where it fits best.
I like it flanked on one side with a couple of 8×8’s.
