I think with all your posts you are certainly headed toward a beautiful creation! (Starting with that wonderful sewing space you have, with all those windows and everything on hand. Only a little envious.) I wouldn't go to the fabric store without having a specific pattern and budget in mind. Read the pattern and check the supplies needed. Then check off what you already have. Don't forget the batting and the backing fabric. Go shopping with a plan, and check the list twice.
My personal experience on my first quilts was to get only what I needed in order to be less frustrated and overwhelmed by the process. Everything fell into place after that. I was fortunate I inherited and given many sewing things, and found incredible boxes of sewing stuff at garage sales over the years. The LQS fabric and thread 'stashes' came later.
Keep us posted!
