Your space is beautiful. I would use that glass topped dining table to sandwich my quilts. Until I moved into the largest bedroom for my sewing room I used my glass topped dining table to sandwich my quilts on.
I bought a large fold out table from Joanns and now use it. Everything is confined in that new room. I have kitchen cabinets, upper and lowers and a 90" countertop all in my room. I have have two large closets with wire shelves for my fabrics, batting, scraps and etc. I haven't taken any pictures of it yet.
I have a sewing cabinet just like yours.
