I used parts of the forms Dad built for the shed stemwall and the forms the crew used on the storm room to make forms for a raised flower bed behind our round flower bed in the back yard. I built the west end, then the east end, tore off the angled ends of those forms and reassembled pieces to make the long north side. Then it started raining. It took a while for things to dry out, so I could move the forms to pour the south side. I used re-bar to tie all the sections together.
