My interpretation of sewing room vs studio just raises the level of sewing to more of an art and many people that sew are really fearful of being artists, which they indeed are. Why not raise the level of what we do rather than saying I sew. Creating quilts in a studio has more richness and sence of quality to it and isn't that what we all strive for. Even if our studio is the dining room table it is still your studio where you create art. If we say we are successful and act in a successful way we are more likely to do be more successful in all we do.
It is not hoity toity, snobish, or being better than others.
It is a state of mindfulness and allows me to perform better.
