Usually, while all of a big brush (thick brush) are used (dissolving and removing all glue) (in the case of the fude with short coat intentionally left on the root in order to strengthen the elasticity, glue is often left at the root of the fude), only the top of a small brush (thin brush) is good to be used.
通常、大筆（太筆）は穂を全ておろす（ノリを落とす）が（根元に短い毛を意図的に残し、筆の弾力を高めているものに関しては根元を固めたままにすることが多い）、小筆（細筆）は穂先だけをおろすのが良い。
