We are slowly working on the garden which was virtual wasteland when we moved in. I am gradually creating a cottage garden from the stark long rectangle of grass but the patio is made up of square slabs (think paving slabs) and it is just a rectangle that spans the width of the house. There are some narrow borders either side and I have various pots out too. We have a large garden table and chairs taking up about a quarter of the area. What else can I do to soften the space? It looks so bland and stark 
Thanks!
