This Sweet Birthday Party Is Perfect For Any Kiddo Who Loves Rainbows and Hearts

"I was really busy with projects at the time of Kate's party, so I didn't get to do all of the fun DIY party craft ideas that I had hoped, but I was able to create a new printable collection for the theme and incorporated cute cupcake flags, straws flags, a 'happy birthday' banner, and other cute details," Kim says.
