On what kind of paper do you write on?  

I prefer paper with lines and margined as I feel neater that way. If I am going to write on a plain paper then it won't look neat. I can't write without line to guide me.

I like using papers with lines. Because if I don't my writing goes to different directions and it's not very pleasing to the eyes.

I've recently started playing around in an unlined scrapbook, and the results are quite interesting. For instance, I sometimes start doodling cartoons of characters I intend to write about, or enhance some of my writing ideas with drawings. Unlined paper does give you a lot of freedom, if you don't mind the writing sometimes being a little skew. Otherwise I use small notepads that I can slip into my handbag.

I like to write on yellow paper with line.It makes me feel peace.

I need paper with lines, otherwise I'm all over the place and sometimes I won't be able to read my own handwriting later. I usually write in notebooks and journals rather than on regular loose-leaf paper. I have this journal OCD where I need to completely fill up all my notebooks before I lay them aside forever. Which actually isn't a problem for me, because I'm always writing.

Plain white paper just as you. I agree!!

I have to have paper with lines or my writing is crooked! When I find some stationary I like but it doesn't have lines, then I put a piece of lined paper under the sheet I want to write on. That way I can use the more eye-appealing stationary and still keep the writing straight as well!

I like to write on lines with margined papers but when I am writing an essay roughly, I prefer the paper to be plain white paper. I dont know why is that but I got used in this way.
