11 / 11 Ⅹ. One possible version:
I am crazy about DIY ，and I often do some things with my own hands. Sometimes I have to read the instructions carefully. Last week ，I thought my bedroom was boring ，so I decided to paint it yellow. My mum told me to stop ，but I kept on painting until the walls and the ceiling were all yellow. Yesterday I put up a shelf above my bed ，and put many storybooks on it. Now ，it is very easy for me to get the books because I do not have to go to the study for them.
All in all, I like DIY very much.
