I would employ savvy storage solutions. Consider how the rest of the house is laid out. Bring your aesthetic into the space. I'm not a fan of most sewing furniture. You can get better quality second hand and repaint it to your specifications. Employing zones is a wise choice. Designating a specific area for sewing, quilting, cutting, etc will bring symmetry to the space. Most importantly, consider the necessity of breathing room and your specific creative nuances in turn. If you abhor clutter don't stuff it to the gills. If you're overwhelmed by visual stimuli then tuck the fabric away.
Finally, make it yours. Decorate. Use attractive colors on the wall and decor. Be mindful of your lighting. Extra never hurts. And if you're inclined to be near a window consider the seasonal changes and make adjustments when the weather cools.
