Step 1: All you will need!
Step 2: Free form
You will need 2 heart shapes, one slightly larger than the other.
Since these will have to nest together make sure that the larger one is big enough to make room for the cardboard core and tape layers.
Cut the original heart from cardboard then flip it over and trace the edge on another piece.
Cut the larger one about 2mm outside of the edge of the smaller one.
Step 3: Box top
Use several small strips of tape to secure the strips around the edge of the larger heart.
Add more tape to secure the strips.
Cover all the exposed cardboard with tape strips.
Trim any folds with a hobby knife.
Flatten and cover all exposed cardboard. with duct tape... keep all tape as smooth as possible
Step 4: Box
Step 5: Make it pretty
Step 6: Add contrast
Step 7: Make a rose
Fold one corner in as shown
Fold an adjacent corner in as shown.
Trim the point round.
Roll the center petal into a tight cylinder.
Add a second petal to the roll but fold small sections of the sticky section near the "stem" together to create texture.
Continuing wrapping petals and folding the base to cause the petals to flare out from the center.
Add as many petals as desired until the rose takes shape.
