Four years ago, my husband and I created a hobby room (2 tatami mats each) in our living room (8 tatami mats).
It's all my husband's DIY. My husband also uses a sewing machine 😆

Although it is smaller, it is more convenient and comfortable ^^
It's a 6 minute video, so I'd be happy if you watched it till the end (^^♪
