Pop up box cards

 I love making pop up box cards and here is my favourite size card. It folds so easily into a 6" envelope - providing I don't get carried away with the embellishments - and then it's a 7" for comfort! Like this time (LOL)

You will need:

1 sheet A4 card - 250-300gsm, scraps of  thick acetate, red liner tape, design paper and images of your choice

1. Cut A4 card to 5 1/2" wide by full length and score at 2, 5 1/2, 7 1/2 and 11
2. Turn and score at 3" but miss the widest section - if you make a mistake, just stick another piece of card over the top of the back  to support the fold.
3. Cut away the bumps of the scores down to the horizontal crease (2 1/2 " creases only). and the hatched section to make a tab.
4. Fold and burnish
5. Add red liner tape to the tab. Fold, press down to adhere
6. Cut 3 struts 1/2" x 4 1/2". Score  at 1/2 and just shy of 4 1/2" . Fold into Z shape  and burnish
7. Glue struts inside the box just under the edge going across from left to right 
8. cut supports for die-cuts etc from thick construction acetate approx 1/2" wide x 3"
9. Decorate as wished.
