You can find a ton of Welcome front porch signs, but how about a sign stating what you really want? "Go Away" And to at least make it a bit more commical "I'm Introverting" is at the bottom. I originally made this first sign for my Marine husband, but now I am a licensed USMC Hobbyist seller, so I can now sell them to you. 
 
This sign is approximately 5ft tall by 1ft wide. 
 
This sign is made from repurposed pallet wood, and you can choose to change any of the paint colors, if you prefer, for free. (You must email me BEFORE ordering if you want to make any changes, to ensure that it is a change that I can accomodate. Once ordered, no changes can be made to the order) I hand cut the EGA and letters on my scrollsaw, and seal everything with quite a few coats of a matte enamel. This coating helps protect wear and tear from outside elements, but since this sign is made of wood, it should not be directly in the elements. Under a covered porched or even inside is the best place to have this sign last many, many years.
