2-2. Things to prepare
c.Bunchin, 文鎮 (paper weight )

Paperweight is a tool to prevent paper from moving. So heavy things can be used instead of paperweights.
(Japanese)文鎮は紙が動くのを防ぐために使うものです。ですから重いものなら文鎮の代わりに使うことができます。
d. Paper for calligraphy
You are best to use paper for calligraphy.They are called "hanshi,半紙" "shodo-hanshi書道半紙". The approximate size of the paper : L33cm,13in, W24cm, 9.5in.
But if you practice kanji and big size characters, you can also use newspaper. Newspaper is suitable for practice because it is moderate blurring. I like to practice with newspaper. If you practice small size letters and hiragana, you can use copy paper. In that case, less bleeding paper is suitable.

(Japanese)書道用の専用の紙を使うのがベストです。しかしあなたが漢字や大きい文字の練習をするのならば、新聞紙も使えます。 新聞紙は適度なにじみがあり書くのに適しています。もしあなたが小文字やひらがなを練習するのならばコピー用紙も使えます。その場合はにじみの少ない紙が適しています。

Please refer to the picture below for beginners brushes.In the large brush: A brush whose diameter is 11 to 13 mm is suitable.
No.3-12.7mm-most suitable for four letters on hanshi (standard-size calligraphy paper)

The colors of the brush hair of the writing brush are different by materials . The white one is goat's hair and soft. The brown hair is harder than white hair. And it is easy to use the brown one than a white one. I encourage beginners to use brown hair brushes.
