Good for you!! Agree with above - go vertical. Don't forget the "under" as well ... under the cutting table, under the sewing table, under the ironing board (or an ironing "shelf").
Also try to utilize things that can be moved. For example an ironing board that folds up into the side of a shelving unit. Shelving units with slider doors that can double as a design wall.
Plan out the things that are larger and necessary first - sewing and cutting table. Then work around those.
