"Quick and easy Valentines a preschooler (and his well-meaning but lazy mother) can make for his 16 classmates. Preferably more creative than your standard construction paper and doilies."
How about construction paper and random items from the produce aisle?
I've seen stamps made of vegetables here and there lately and wanted to try it myself. Ignore that head of lettuce there above; it didn't quite work out. Instead I ended up with a starfruit star and a celery stem rose.
So cut some hearts out of construction paper.
Put a stamp on each heart.
Since the stamps are a little, uh, abstract--and have a tendency to go even further in that direction when a preschooler is in charge--I made little drawings to help solidify the stamps' rose and star identities.
Add a sweet star- or flower-related saying and that's it!
Seriously, this project took more time to blog than to execute. Which incidentally meant that it was just right for my kid's attention span. She was delighted with it.
If produce stamps aren't your speed, there are tons of free printable Valentines out there:
Color Theory Valentines from Mer Mag
Love Mail Valentines from Noodlehead
Class Party Valentines from One Charming Party (via 17 Dove Street)
Looking for more Valentine ideas? Check out my Valentine board on Pinterest. (Though it turns out that few of those ideas are truly quick & easy...which must explain why the house belonging to well-meaning but lazy me currently features the wintry dregs of Christmas and a couple of bedraggled paperwhites.)
