Yesterday, I visited a family woodworking shop of excellent quality about 25 miles from here. Their beautiful, hand crafted, oak, solid sewing cabinet is wonderful-and costs $580.
I asked if it was possible to make one without drawers (like what I have now) and is wide enough for me to sit in front of the needle.
Yep, $300!
I also looked around for a large old desk or table-maybe one possibility.
I'm glad I'm still looking thanks to all your info. Haven't decided yet!
