This is kind of a long story but I recently hand washed two Jos. Banks merino polo sweaters (tag said dry clean only). Both sweaters had tiny holes show up after they dried and had to be discarded. I had the same problem with a Gap merino sweater last winter. At first I thought it must be a moth hole but now I'm wondering if there is occasional weakness in the yarn of lesser quality sweaters. I haven't run across this problem before but I'm new to merino. Comments?
