It is so strange. DH thinks there is some sort of chemical reaction between the liquid bluing and the soap. The base for the home made laundry soap is a Fels-Naptha laundry bar which is a yellowish color. Not this dark though. I will say this, the clothes are much softer when washed in the home made laundry soap. As long as it is not harming our clothes I will continue to use the home made until we run out and either not use the bluing again or will be trying another laundry recipe. The other option is to add a few drops of bluing to each load I wash of whites to brighten them. I will keep you posted :)
At the moment I am working on machine quilting the baby quilt and hope to post an update on the quilt tomorrow!
