My only actual sewing this was was something I am calling bookcase curtains.
I have a plain white bookcase which ended up in the living room. It had been in the study/guest room but had to come out once the bed went in. Since it houses folders, manuals, magazine and bankers boxes plus a wire basket of padded envelopes it wasn't too pretty and for a while I had a throw over it.
This is quite a nice idea if you have a bookcase like this storing fabric which you want to protect from the light, though you might want to use something a little thicker than the cotton curtain lining fabric I have used here. You could also have pretty items on the higher shelves and have a curtain just for the lower shelves, used to store plainer things.
I overlocked the fabric all the way round the edge, stitched a narrow hem up each side and a slightly deeper one at the bottom. The top has a 3" casing with a row of stitching 1/2" from the top. The top row of stitching creates a little ruffle above the pole to close the gap at the top.
