Gather cardstock, colored paper, scissors, glue, ruler, and pencil
Fold a cardstock sheet in half to make the card base
Decide where the pop-out element will sit inside the card
Cut a small slit or two parallel slits on the folded edge of the inside panel
Push the cut section inward to form a pop-out tab
Fold the tab in the opposite direction to create a support
Cut out the pop-out shape from colored paper
Glue the shape onto the pop-out tab
Add extra layers or decorations to the shape if desired
Close the card carefully to check that it folds flat
Open the card to test the pop-out effect
Trim or adjust any parts that catch or stick out
Decorate the front and inside of the card
Let the glue dry completely before handling
Repeat with multiple tabs for more pop-out elements
