The arrow could be a fun pencil or straw or a glow stick.
You could insert a pencil or a lollipop through the butterfly wings.
If you don't have a heart shaped stamp you could use stickers instead.
You could also use the fun rulers with stencils or colored rulers.
This one is my favorite! The head is a lollipop wrapped in tissue paper and I think Ava could help with a lot of it.
Happy Valentine's Day!
