How to Make a Trimcraft Exploding Fold Card

A few simple paper folds will create this exciting card shape with a wonderful surprise hidden inside for the recipient. Created & Written by Kathy Hodson, Trimcraft.

Time to make: 25 – 45 minutes, depending on embellishments

Skill level: Intermediate

You Will Need:

Step 1:

You will need two 12″ x 12″ papers from your chosen paper pad. I have used the First Edition Sweet Nothings Paper Pad as double-sided papers are perfect for this kind of project.

For the inside of the card, I chose a paper pattern that would be suitable for stamping onto, so bear this in mind when choosing your papers.

Step 2:

Trim the paper you want to use for the inside of the card down to 28cm square. With the inside paper design facing up, fold corner to corner and crease along the center. This will create a diagonal line across your card when it is rotated square on.

Step 3:

Open the paper out and turn the paper so you can fold the other corners together. Crease along the other diagonal fold. Open out again so that your inside pattern is on top and the paper is square on. Fold in half, taking the bottom edge over to the top edge. Score and fold.

Step 4:

Using the natural direction of the folds, bring the paper into a triangle shape. To do this, the diagonal folds will need to be valley folds (fold into a V shape) and the fold across the center of the paper will be a mountain fold (sticking up). You will then have a triangle with the point at the furthest point away from you. Make sure all the folds are creased properly.

You can use a bone tool to do this.

Step 5:

Turn the folded triangle so that the point is closest to you and the longest edge away from you. Mark the center point of the longest edge of the triangle. Take the top left corner of the straight edge and fold it into the mark at the center point, taking care to only fold over the top layer. Repeat with the corner on the right of the long edge. Turn the paper over and repeat on the other side. Each of the four corners now need to be opened out and folded back in on themselves.

Step 6:

You will now be able to open the paper to reveal the ‘exploding’ center and it is ready to stamp your sentiment inside. Don’t forget you can easily ‘mask’ a stamp if you don’t want to use the entire image or sentiment. Cover the area of the stamp you don’t want to use with low tack or washi tape before inking your stamp. Remove the tape and stamp as normal.

Step 7:

To create the outside of the card, take your second sheet of 12″ x 12″ paper and trim or cut it in half to 12″ x 6″. Fold in half to create a 6″ x 6″ card blank and ensure the fold is well creased. Decorate or embellish the front of the card, bearing in mind that your finished card will stand upright for display with the opening at the bottom and the fold at the top.

I used Trimcraft First Edition border dies cut from the green paper in the Sweet Nothings pad, together with a topper cut from and the topper sheet in the same pad. I finished the card with adhesive pearls in the top left corner and a bow in the top right.

Step 8:

When fixing the two pieces of paper together, the corner of your inside folded paper will need to be as close as possible to the center point of the fold on the outer paper. You can use your preferred adhesive to do this. Permafix tape will keep the pieces together securely, whereas a wet glue will give you a bit of time to manoeuvre the paper into place, but will need more time to set and dry.

Your finished card will look great and hide a wonderful secret inside to surprise the recipient!
