Do you want to use up some of those stacks of chipboard...how about heart magnets?
This picture shows them on one of our old vintage windows that we converted into this awesome, dry erase, magnetic and chalkboard display board.
The magnets were embellished with ribbon, brads, buttons and some were stacked and layered on to each other. You can use this same idea on any shape of chipboard. How fun to make magnets for every occasion.
