Constant Crafting

Does anybody else have children who feel the need to constantly cut, color, deconstruct, and construct during all waking moments?  I'm sorry, but I really am getting tired of sweeping up tiny, little scraps of paper.  We can't even finish a box of cereal without one or more children asking to "recreate" the box into something unidentifiable.  I love my kiddos at this age, but I can't wait until they actually make something besides a huge mess with their creative genius :0)
