Start by spreading out the colorful construction paper on your work surface. Pick a color that will make the paint stand out, like a bright yellow or a deep blue.
Help your child place their hand and part of their arm onto the construction paper, spreading their fingers wide.
Trace around their hand and arm with a pencil to create the outline for your 'henna' canvas.
Next, carefully cut out the handprint and arm. This will require adult supervision, especially for the little ones.
Pour some washable paint onto a tray. You might want to use a few different colors to mimic the natural variations found in henna paste.
Now for the fun part: dip a Q-tip into the paint and start decorating the handprint with henna-inspired patterns. Think swirls, dots, teardrops, and loops. Encourage your child to cover the fingers and palm with their designs.
Continue adding designs until the handprint is filled with beautiful patterns. Remember to switch Q-tips when changing paint colors to keep the hues bright.Once the masterpiece is complete, set it aside to dry.
