Pocket card made with leftover strip from a 12x12 sheet of black cut to fit envelope. I fold the strip to fit whatever size envelope I have, trimming width as needed. I plan what stamps I'm going to use so I know how much of the pullout tag needs to be seen above the front of the "cuff" openening. Trim front "cuff" as needed to show the main stamped portion of your tag. I than glue sides of pocket with a narrow 2 sided tape strip. It's hard to give sizes because it is always different depending on envelope size & what headline you will stamp. The tag part of the card is done in 2 layers to give it "body." Naturally cut the first layer to have it slip in the pocket without dragging on the sides (1/4 to 3/8 less than pocket side). When using 2 layers of the same color for the tag I added black ink to the sides of the second layer to give added demension. Than punch a hole in top for ribbon or any pull you are using. I added scrap black & grey stripe paper for contrast for the card opening as a "cuff". Than decorate as you wish. Sometimes I add stamping to the front of pocket either flat or a raised portion for dimension.
