After a few modifications, I've finally settled on this design. There are two Cotoneaster in the front that I've had for about a year. A week ago I planted two new ones in the back. The bigger ones were just as small when I first got them. I like this structured look, of course there's no science to it, it's just my personal hobby.
There is a second hand bookstore near my house that I frequently visit. Aside from finding rare copies of books that are long out of print, t's always so nice to grab a 80 year old book for less than 10 bucks!
