I bought a lovely set of vintage buttons at Yarnover 2013 with no planned project but just because I loved them. Now I finally know what they want to grow up to be: an Ombre Cardigan. This weekend I wound the 4,000 yards of lace weight yarn (yes, you read that right) and created my swatch. Good news, though, is that the yarn is held double. Love how the TFA Aurora and Lucky Penny are combining…
