Perhaps a sewing desk that has an extension that goes in back of your machine-so you have more room for quilting a quilt-if you desire. Also with a dropout for your machine-to make it level with desk surface. Plenty of great lighting! Daylight bulbs are great to help show true colors. Do you need a fan or A/C installed-? Plenty of grounded outlets. A comfy chair with good support. Do you need hubby to build you a big board for your ironing board? Build a cutting table with storage underneath? Put up a peg board? Or a portable design wall?
The "Mission: Organization" thread has lots of really great ideas~~~
