Magnetic Valentine's Conversation Heart Pins

Celebrate Valentine's Day in style with these fully-embedded magnet conversation heart pins! I wanted to make something cute and whimsical for my kid (she loved it) to wear to school and this is what I came up with.

Each pin (one front and one back piece) uses two (2) 15mm x 3mm magnets, embedded inside the middle of each heart for efficiency, looks, and to avoid any danger of being swallowed by children or people who, I dunno, like the taste of magnets and bowel perforations. 

Two designs are already on the bed, as well as a third, blank heart for customization. Simply select the blank top piece, click text shape in the tool bar, and adjust font, size, and words you want to add. Then hover over the heart and, once the words are in place, click to set. Then it's as simply as painting the words.
