Fancy Folds: How to Create an Explosion Card

Surprise your friends and family with a card that's bursting at the seams — really! There are no real explosives involved, but explosive cards are tons of fun because no one suspects the inside of the card to pop open bigger than the card itself. With just a few folds and inverted tucks, your next card recipient will be thrilled and amazed by your creativity!

Wow friends and family with a card that explodes open to reveal heartfelt sentiments!

Before you get started...

Keep these tips in mind when making an explosion card:

An 8½" x 8½" block of card stock serves as the folded insert, fitting perfectly within a 4½" x 4½" card base. Larger or smaller cards can be created by adjusting the size of the explosive panel and card base to fit.

Use one-sided patterned paper if a color or pattern is desired on the folded sides. Otherwise, use plain light-weight paper, as heavy card stock is harder to fold and will result in a thicker finished card.

Crease each fold firmly with a bone folder. Doing so will result in a flatter, more professional finish.

All stamping on the insert should be completed before folding to ensure solid impressions where fold lines will appear. 

Once assembled, the card will open flat for easy signing so there is no need to write a personal message before assembly is complete.

Explosion card tutorial

Step 1:

Using a zero centering ruler, if available, center a 3" x 3" sticky note on the back side of your patterned paper to serve as a mask. This will mask an area for a sentiment and short personal note. If a longer greeting is desired, adhere a larger mask, or omit it entirely. If omitting, continue to Step 3.

Stamp images over back side of patterned paper. Once stamped, remove the mask and stamp desired sentiment.
