Let's see.... my quilting room is in the basement with a dehumidifier running constantly this time of the year, so no damp smells. I usually have a plug in going with whatever scent happens to be handy, usually something light. Like some of the other quilters here, I also share my space with my hubby. Alas, it's not the office space. He is an avid outdoorsman, so the other half of the basement frequently has muskrat or beaver hides drying in the spring or fall.....hence the plug-in! I'm always happy when the day comes to take the hides to the buyer. And it is nice to be working at my sewing table while he is nearby so we can chat.
