The Holey Moley Duster Crochet Pattern Hey everyone and welcome to The Holey Moley Duster! This is a perfect summer cardigan where the holes are the feature and not the flaw! It’s made to measure so you can use any yarn and any hook. I have based the yarn yardage on aran acrylic yarn (category #4) and a 6mm hook, but you can use any ply of yarn that you wish. There is also a full-length video tutorial on my YouTube Channel if you would like any extra guidance. I look forward
