You need to used a 12x12 sheet of DSP or cardstock to make this card. However, you will be able to make 2 cards with 1 sheet! So there's no wasting the DSP or CS.
Alright so here's a quick instruction on how to make the Double Gate Fold.
1 sheet of 12x12 DSP cut to 6x12
Take out you Simply Scored Scoring Tool, and with the 12" side on the top, Score at 2", 4", 8" and 10"
Turn to the 6" side and with a pencil, mark at 2 3/4"
Turn paper all the way around to the other 6" side and mark again at 2 3/4"
Now fold at the 4" and 8" score marks. just like you would fold a card in half.
Grab your paper trimmer, now this might be a little difficult, but we are going to make the diagonal cut.
You want to take the fold at the 8" score line and line it up on the groove of your trimmer (where it would cut) and then turn it at a diagonal to the 2 3/4" mark we made with the pencil. Make your cut. Repeat on the 4"score line fold.
Now you are going to fold back (opposite) on the 2" & 10" score marks (accordion fold) and that creates that z fold.
Take the 2 cut strips and line them up along the inside of your cars, you will start at the 4"/8" scored lines with the highest cut and the outside edge should finish with the smallest points. It's a little hard to see in the pictures, but the bottom of the cards all have opposite side of the paper showing.
I have attached the link here to a SplitcoastStampers YoutubeVideo that shows the direction on this card style. It will help to see the card made.
I used a similar design on my card. It worked perfect.
I stamped the outside I stamped the Making Spirits Bright with a coordinating ink color (depending on the paper design) and on the inside of the cards the branch and ornaments from the Among the Branches Stamp Set and the greeting from the Versatile Christmas Stamp set.
My family and closest friends received the card with a photo of our family on the inside. While others received the card with the stamped inside.
