Perhaps your children will make a red rose for Valentine's Day? Alternatively, choose any colour they like to add a rose to the stem; roses come in such beautifully different colours and patterns.
Lace around this lovely red rose for Valentine's Day, Mother's Day or summer, perhaps. Cut out and laminate, then punch holes around the edge. Older children could use a blunt needle to punch smaller holes along the inside black lines and stitch along them with running stitch.
We've got step by step instructions here which will teach children how to draw a pretty rose - useful for Valentine's Day, Mother's Day, St George's Day, or for nature study!
