This is the room my husband built for me. He did all the cabinets and bookcase. Also put a sink in the corner upon my insistance :D I love all the natural light from the windows. This room was supposed to be a guest room but my dh said he thought I would enjoy it far more as a sewing/craft room than an overnight guest would - he is right on!
I have a large window that givew wonderful light to my working space on the large table.
My large working table was once in a local dept. store. I purchased it nearly 30 yrs. ago and it has been in use as a sewing table since. It has large pull out shelves on 2 sides - great for storing all my "stash"
My serger and sewing machine sit on a white table by a window - the white table makes it easier to see when sewing. My dh made the thread holder that sits in the corner of the table.
