Draw the handprint
Place one construction paper on a level surface and cover all corners with a small object to make sure it does not roll over when you are working on it. Ask the children to firmly place their hand in the centre and draw the handprint with the help of a pencil. Repeat the action with all the young ones. Make sure the drawings do not overlap as that would not give you the desired result.
Cut out the drawings
Carefully cut down the handprints on the construction paper and set them aside. Make sure you cleanly cut them out as that would give the art a great and neat look.
Use the red paper to cut out a heart shape
Draw a heart shape with a pencil on the red construction paper and cut it out.
Paste the handprints on the heart
Now place the heart shape on a level surface and paste the handprints on it one by one. You can either paste them together in a same line or use them on the edges. Make sure you use reasonable glue for this as using excess glue may result in damaging the paper.
Decorate the art
Finally, decorate the art as you desire. The best thing would be to write the names of the children on the handprints. Another good idea would be to write a decent Valentine message on the remaining empty areas of the construction paper.
