I don't have much extra cash for specialty threads. I have accumulated plenty of DMC that needs to be used. I bought some skeins of Valdani because it was advertised as colorfast and because it was on sale (online). There is no local needlework shop here--the nearest shop is one and a half hours away.
I used some of it on my HOE "ABC Exchange 2010." It frayed and broke several times. I will not buy this thread again.
I have been using DMC embroidery thread for 38 years, and never it has frayed or broken.
