I spent the whole weekend decorating and it was difficult.  You have to consider a lot of things and details.  After part of the house was finished I realised I had not takend some things into consideration.  For example, my bathroom was not designed well.

Last weekend

I went out for buying some decorationed materials for my new house [for whole last weekend] (it doesn't make sense). Decorating the house is a very troubled matter, you must consider a lot of things for it, especially for each of the details. After the part of the house wais finished, I always thinkought my consideration is not careful for it (it does not make much sense too). For example, my bathroom is not be reasonably designed.
