From my mother's sewing room. She was an avid seamstress and did a lot of machine embroidery, as well. This lot includes 7 full spools sealed in their original plastic wrappers and 21 partial spools. Following is a list of the color number and my interpretation of the color, as well as my estimation of the amount left on each spool. 

The price I have listed these for is based on:

7 full spools @ $2.50 = 17.50

18 nearly full spools @ 1.95 = 35.10

1 mostly used spool @ free

Total $52.60 (Includes shipping cost)
