These belonged to my mother in law and I already have a ton of vintage sewing baskets.
The yellow thread holder has some of the wooden spools of thread that were in it when I got it. It measures 13" x 8" x 2 1/2" and is in good vintage condition.
The red one measures 12" x 10" x 6". The 'shelf' is cracked at the edges but still stays in place. This one needs to be cleaned up and there is a burn mark? on the top.
