Do your kids have favorite leaves that they find in the fall? Turn them into clever art with a little glue and paint! DIY Painted Leaf Art for Kids
Gorgeous DIY Paper Leaf Garland. I found all the paper colors here too. www.paperandmore.com They let you order singles (as many as you want) and have flat $1.50 shipping for them. They're like 50 -75 cents a sheet, great for when you need several colors.
Valentine Garland ...could easily make with a deck of cards, ribbon and scraps of fabric
