The Mermaid had 3 dimensional hearts for fish and Hello Kitty has 3 dimensional hearts for balloons. Here is a quick tutorial on how I made it.
I will be using the hearts I made for the Mermaid cards
First not really a step but I thought I would throw it in... I made my own black and red polka dot paper.
Then I took the medium punch or is it large.... cant remember from Hobby Lobby and punched out 5 hearts and folded them in half
Put glue on one half and press it to another folded heart
Glue all five hearts like that. Dont glue the last two gether if its for a paper project and needs a flat surface to glue to your base. If you are making something like an ornament then glue the two heart sides that were not glued to another heart shape together.
Fluff up when done... or flatten it to mail
