I have 4 hand embroidery blocks that my mother started to do for me when I was born. She finished them up last year and now they are going to be for her GGD who is 1. I have been tasked with putting the quilt together (I do not mind) but I was wonder what is the best way to wash/clean them. There is one that is more stained/dirty then the others. No rust spots on any of them which we are happy about. Just am not sure the best way to go about cleaning them before I start the quilt. Any suggestions are greatly appreciated.
