As soon as I could move around the house without waking my husband or the houseguest, I gathered up some empty cardboard boxes from the garage and emptied all the envelopes of photos and the photo albums from the drawer on the bottom of my bookcase in the den/office, and stored them in a closet. Now that drawer is the home of all works in process. It also has a self-limiting function: as soon as the drawer is full, no more starting new projects until a few are finished!
(This isn't my den - just a picture of the bookcase from the manufacturer. But isn't it cool!)
While I'm at it, I'll add the manufacturer's picture of my desk. I LOVE this desk. My sewing machine is stored in the computer compartment on the lower left side. When I got this office furniture, my husband suggested sewing on the desk, but I'm too scared of scratching it up. I display my Coimbra pottery on the shelves inside the upper glass doors, and the top is large enough for my laptop, my gemstone globe that my husband got me for Christmas last year, my Tivoli radio (another big fav of mine) and a quilt-of-the-week desk calendar. The only thing that isn't perfect is the desk light. I really need to buy an Ott-lite desk lamp. The one I have now is halogen, and while it really puts out the light, you can pratically get a sunburn from the heat coming off it!
