I chose a vintage distressed look but you could use bright materials for brighter hearts.
A heart made from Hersey Kisses.
Open a couple of kisses carefully. Eat the kisses. (must do that). Then take the wrapper or wrappers (number of wrappers depends on how big your heart cookie cutter is) and mold them into the heart cookie cutter. Lift cookie cutter and voila you have a foil heart. Flatten out the little white note/paper and glue it to the back of the foil heart. Now you can transfer the entire heart to your favorite card or garland or whatever you can think of.
Wonderful! Now you have a wax heart for embellishing. Side note: I sprinkled a little glitter on mine when it was in the mold.
A wax seal heart.
A cling wrap heart.
This was a mistake I glued the wax heart onto a pennant and didn't like it so I took it off and then I loved it.
So sometimes mistakes are good.
