My 2nd card is CASE'd from a swap my upline Betty made for our recent Stamp Share and uses the new Envelope Punch Board:
Stamps: Snow Day
Colors: Basic Gray, Pool Party, Whisper White, silver
Accessories: Winter Frost Designer Series Paper Stack, Envelope Punch Board, Silver 1/8" Ribbon, Rhinestones
To make the card look like a file folder, I put the cardstock (with DSP already attached) into the Envelope Punch Board to cut the outside corner. Then I flipped it over and punched it at 3". I used the Stampin' Trimmer to remove the top left corner, which left the "tab". The back side of the Envelope Punch Board has a corner rounder punch, so that was used to round all the corners. I LOVE this new tool! Did I mention it makes really cute envelopes, too?
