What a great space. What ever you do, know you will rearrange the space several times before you are satisfied.
Will you have a spot for a design wall. This and the sewing station should be near to each other. Ironing station to the right or left of s-machine depending on being right or left handed. Fabric near to the iron station. Cutting station near the fabric . I like to have the iron so I can work from both sides. It really doesn't matter where you place things as long as related things are close at hand as you set the room up. Hope some of this helps. It will be great!
peace
