What are Tunisian crochet hooks used for?
Interchangeable Tunisian crochet hooks are used for working larger project mostly, including afghans, and also for working in the round. You can purchase two sets, or two of the same size hooks and cap each end with them to create large two color projects and graphgans.
Which yarn is best for Tunisian crochet?
Tunisian Crochet and Yarn
Usually a worsted weight acrylic or wool yarn was crocheted with an “afghan hook” smaller than a size I tend to use. (I usually start with a size K/6.5mm hook for medium weight yarns and then go up or down hook sizes from there.)
