Little Blue Box of Happiness with two different heart designs for the envelope.
Here is the PDF of the pop-up box.
Here is the .Studio file. I used cardstock for both the card and the envelope.
Glue the smallest box together and attach the ring insert to the tabs as shown.
Glue the top together as shown on the left. The ring insert is on the right.
Make the bottom of the box...shown on the left.
Insert the bottom of the box with the tabs INWARD...this is needed for the ribbon to be threaded on the bottom.
Here is what the inside of the box looks like after the ring insert has been placed inside the box.
A ring can be placed inside the box.
Or a charm...glue two designs together. The box cover is shown at the bottom of the above photo. Notice that the top is folded outwards. When this card is folded closed, please make sure all of the pieces fold outwards for the box to close correctly.
Thread an 18 inch length of ribbon through the bottom of the card and back.
Here is what it looks like after it has been threaded through the bottom.
Put the top on the box and close the card partially. Tie the ribbon as shown.
Use a glue tick to glue the contrasting color to the bottom. The glue stick will not warp the paper as much as other types of glue.
Completed pop-up box card.
To make the envelope, fold the sides as shown.
