I am either getting arthritis in my left thumb or the tissues are more or less permanently damaged from using my phone (you can see why I find this too embarrassing to get checked out) & I nearly dropped the roller a couple of times. "all" we have left to do is the dining room and the kitchen. The dining room is huge but easy. The kitchen will probably take longer to mask than to actually paint. There's a reason I've been putting it off for three years...
