Sometimes, too many choices is a curse. Why don't you concentrate on the big choices first. Lighting, color and flooring. Then maybe your organization. On your color, think about what would really make you happy everyday to go into your quilting room. Or, do you want it to set off your finished pieces that will decorate your room. If you liked the green, why did you eventually not like it. Is it the wrong shade, too dark....
Lighting, now that you've used the room already, you know where the lighting is lacking. Go with your gut on what you'd like.
You have the flooring picked out. One problem solved.
Organization, again, you've already used the room. Think about what it was missing.
Did you not like anything about the room before the disaster? It really was a pretty room. I hope you have fun decorating and that you end up with the room of your dreams.
