I've always called mine "my lair". A friend told me that since I have a dedicated room for my quilting & sewing I should call it my studio. I still like calling it my lair though!

My bedroom. For the time being. Once my downstairs apartment is vacated I will get the living space as mine and Lulus and df will bring my washer and dryer upstairs so he can have the man cave.

Going to sew

Mine is the "other" room.

Mine's called the dining room.

I call mine my sewing room. I only let my black cat in there, others are banned.

Mine is the 'mom cave' and I even have a sign on the door my daughter made for me! (it's her old bedroom)

No name for it, but I do have a sign on the door that says not to disturb the sorceress within, lest the dragon be released to wreak havoc on the world.

I call mine my sanctuary

I should call it the money pit for obvious reasons
