On today's June Paper Pumpkin Alternate cards, I used portions of the envelope liner paper to create mats for the backgounds.
On the above card I used portions of both envelope liners.
On the card above I used the twine to hang the banners and no liner for the envelope. I also used an additional piece of Whisper White cardstock 5" x 3 3/4".
Check out the sponged edges on the card and mats on the above card.
I am not done yet, 3 more alternate ideas tomorrow.
