If you find a mistake in my notebook, could you correct it?

Futon isn't a proper noun, so there's no need to captalize it!

Also, be careful about spaces bewtween commas. Instead of: "low , wooden", you would just write "low,wooden". There isn't really a need for spaces between the words and the commas.

Anyway, you wrote so well, I'm very impressed!! ^O^
