By popular demand, I am doing a card class next Tuesday for 2 of my friends at Bible Study. This is the card I came up with; but with its ragged edge at the bottom, it won't stand up on its own. So I came up with an easel for the back of the card. Problem solved!
The side view shows how the easel keeps the card on display. (I used white here so you can see it better.)
To attach the easel, using a strong adhesive between the fold and the outer edge, mount the easel so that the narrow part is flush with the bottom of the card. Open the flap to a 90 degree angle to make the card stand up.
I hope this easel construction makes sense!
