For the first one, I scored 1/2" then 1/4" on four pieces of paper 12" x 1" and made my folds:
Then I placed the four pieces just under the edges of my sentiment, making sure I had pleats exending past the edges on all four sides.
I then added the panel to my card, and added a few embellishments (which are great if one of your corners doesn't come out quite right!)
For the next card, I decided to do box pleats - I scored 1" then 1/4" then 1" then 1/4".
And folded like so:
I then added the strip to my card background.
I added a few border strips and a strip of Dazzles.
