Here are the plans I made up for the fort that I wanted in our yard.
I'd say they are pretty detailed and very precise. NOT. I made them up myself and it is obvious. I just took what I liked from other forts I found online. I didn't take pictures all along the way, but I took a few here and there. The cutest part was how Oliver brought out his tools and helped me all along the way. Our neighbor came over to help a lot too. The only thing we have left to do is paint it.
And here is the finished version. Minus the paint. The boys totally love it.
