At times, I feel like writing on cloth. Thus, here is “Solving a problem swiftly and skillfully” on linen cloth. It apparently originates from an expression, “Cutting tangled linen yarns with a sharp sword”. The last character means “linen”.
ときに布地に書きたくなり、これは麻布で、「快刀乱麻」。元々はもつれた麻糸を鋭利な刃物で断ち切るように物事を処理、解決するという意味らしいです。
