I think that I solved the drama of the bad floss. I had used some floss that was in a wall hanging kit, which would not have to be color fast! I have learned my lesson and will only use floss from "known" sources that are made for things that may be washed regularly.
These are the last ones for awhile, since we are traveling. I gave away all the dishcloths that I have knitted since the holidays while I was at Sister's house, so I have to knit some more, just in case. One cannot be without a stack of dishcloths at the ready!
