I just got accepted into a juried arts and craft show for next month. I'll be bringing hundreds of my notecards. I'm also going to display an enlargement of a loon and an eagle on easels and offer them for sale by orders. I was going to order 16 X 24 enlargements but then realized that your standard frames are 16 X 20. If the customer was going to frame them, this could be a problem? What size would you, who have sold prints, order?
