Pop Up Card Tutorial Lesson 16

Inverted V-Fold Pivot

How to create a rotating element with a 45° v-fold.
Level of Difficulty: Medium

The basic V fold is a powerful pivot, able to rotate a design element a full 90 ° as the card opens. You can use it to move a piece side to side across the face of the card, or to pop something in or out from the fold of the card. It can raise a flag, jump a cow over the moon, or make a rabbit peek out of a hat. A double V can bring a couple together for a kiss, prick up a dog's ears, open arms for a hug, or jump legs up and down.
In this lesson we will make a symmetrical V pivot. This mechanism is most used to hide a design element in the crease of the card, only popping it out when the card is nearly all the way open.
Start with a square piece of paper. (Makes two v-fold pivots).

Black solid lines are cut lines. Dotted lines are fold lines.
Fold and unfold in half vertically, then along both diagonals. Decide how wide you want your tab attachments to be (let's say 1/4"). Measure in 1/4" and draw a line parallel to each side. Cut off and discard the 1/4" segments at the top and bottom. Cut paper in half horizontally. You now have 2 v-fold pivots.

Flatten V pivot. Align centers of v pivot and card base. Glue tabs to card.

In the sample the tabs have been valley folded and glued facing out (visible). They could just as easily be mountain folded and glued facing in toward the center (less visible).

This one, for example, suggest antennae or antlers. Turn it upside down and it looks like legs. As the card closes the blue pieces tuck back behind the V fold.

The candles and number 16 fold down behind the cake when the card is closed. Robert Sabuda pattern. Tutorial for this variation here.
Fishhead Pop Up Card by Crankbunny. I suspect it's powered by a v-fold. The girl emerges from the fishes mouth, much like the candles on the birthday cake, as the card opens.
