Heart Lock and Key Coloring Page

Ages 3+ · A4 · free

A heart-shaped padlock with a keyhole, and a key whose handle is also a heart. Few large shapes and strong outlines — one of the quickest pages here, and one that survives a thick crayon without any trouble.

Two ways to colour it

• On paper. Print the A4 sheet — the PDF has a QR code in the footer so you can find your way back here.
• On a screen. Open the same drawing in Colorful Hearts and tap to fill each area. It works offline and keeps your progress.
