This is my card. I stretched out the three images further across the center and added a sentiment.
When I started my card, I did not have plans for the extra panel (the black one), so I cut the cardstock I thought I would need.
Red - 5 1/2" x 8 1/2", scored at 4 1/4"
White - 4" x 5 1/4"
Red/White gingham - 1 1/2" x 5 1/4"
After lining the back of a piece of red cardstock with a section of Scor-Tape two-sided adhesive sheet, I cut the die-cuts. Because of the adhesive back, the die-cuts were a bit wonky when I took them out of the dies, but I knew they would straighten out once I added them to my card.
I then constructed my card . . .
. . . and added the die cuts.
At this point I didn't think there was enough contrast on my card, so I pulled up the white panel, cut it down by 1/8" on both sides and added a black layer, which I had cut at 4" x 5 1/4". I then added some small black sequins.
I was much happier with this version. CottageCutz dies used on this card are:
