Sometimes I'm hesitant to even share my DIY projects, because they really are just that simple (see examples: here, here, and here). But, then I realized...there's no realizing creativity needs to complicated. It's just a matter of sharing something that someone else might not have thought of before.
So with that I give you the easiest DIY ornament "tutorial" of all time.
Step 1: Buy a Christmas tree.
Step 2: Saw and extra chunk off the trunk.
Step 3: Write the date and "Baby's First Christmas" on it.
Step 4: Go have some hot cocoa, because you saved so much time by not crafting something complex.
*Note: you could also just make one of these from every Christmas tree you get each year. Just sayin.
