Theoretically there's no room for this in the yard. Practically, it had to be done! Once we read it in a book, both the boys and I had our hearts set on making a bean fort.
You make a teepee with sticks, plant beans at the base, and let them twine their way up the sticks. Et voila! A bean fort :) I'll post a picture in August when the beans will be 2 meters tall.
