I've always liked Coats & Clark (cotton covered polyester.) Last week I bought several spools when it was 50% off at Hancock's. I noticed it didn't have as much sheen as it used to. When I sewed with it didn't look nice so I checked the spool. It's now made in Mexico, and is "polyester covered polyester." I don't like it. If anyone wants to donate old thread for charity; I'd be grateful for it and would pay shipping. I make clothing protectors (large bibs) for the Conway Human Development Center (in Arkansas.) This is a residential facility for the handicapped. I put old thread in the freezor and never have had a problem with it.
