I am at home on bedrest and I have to shop online for now. I am looking for corduroy for a Christmas rag quilt and I prefer the tiny lined corduroy. I don't understand what gauge to look for... For example at Joann.com the have 8w to 21 w. Which one is the fine lined cord? Thank you for your help! Oh, if you have a great site for corduroy please let me know. I am not finding many choices online so far. Anna
