Decide on mason jar placement; screw the small piece of wood into the wood slice in this location. Use the drill.
Nail two thin nails into the slots of the hose clamp and into the piece of wood.
Use a hand screwdriver to tighten the clamp around the mason jar until secure.
Turn the slice to the back and add a picture hook to the back.
Use some sandpaper to smooth out the area where you will place the vinyl numbers.
Peel off the numbers needed and stick them on the wood slice in the desired arrangement.
To finish, wrap a few artificial or real flowers in burlap and place them into the jar. Hang the plague on your home outside, preferably in a covered area.

Notes
If you have paint, you can draw some freehand numbers on the plaque with a pencil and then paint them in so you don't to buy the vinyl letters. We just happened to have them on hand.
