Dear K.Korn,
I have shown your sent yarns Nylon and Spandex to Boss.
So Boss wants you to check as follow.
1) To check Nylon whether whole cone black or not.
If not whole cone, how many percentage for black?
2) Use yellow spandex and make product.
After that see the color of finished product whether acceptable to use or not.
After done, please let me know the status early.
