I have a cutting table built into one wall, to use it I just flip out two horizontal supports and pull down the table. I can also store all my fabric inside the cupboards behind the table surface.
There is a sofa bed underneath that pulls out when we have guests staying - currently being made hairy by cats! I also purchased a small tabletop ironing board from Ikea which is just right for pressing seams etc. and I can hang it up on a hook on the back of the door.
On the other windowless wall are more storage cupboards and a desk. The back wall of the desk is a magnetic whiteboard which will be useful for scribbling and posting notes and ideas. The left hand desk drawer is not a drawer at all, but a small pull out surface for my serger and I have an office chair on wheels so I can swivel between the two machines easily.
I have windows on the other 2 walls so lighting in the day is great. For night sewing there are lots of ceiling spotlights and also a fluorescent tube above the desk surface.
So I am loving my little sewing space and am currently working on a top from the June issue of Burda in a brown and cream printed linen from my last post, you can just see it in the photos above - it's nearly there so more details on that next post.
