Gardening- the sequel

I have continued with my concerted effort to maintain a tidy if not beautiful garden. Today I went out with a garden sack and pulled up some weeds and got rid of some rubbish. I have to say that I'm really enjoying it. The only trouble is that I'm now looking at summerhouses and wanting to knock down walls. Hopefully I'll walk before I run...but how difficult can it be to erect a glorified garden shed? ;-)
