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.)
Does using a bigger crochet hook use less yarn?
If you are using the same pattern (same number of stitches and rows/rounds), a larger crochet hook will use up more yarn. If you are going for the same size of project (say a 36 by 36 inch blanket), a larger crochet hook will use up less yarn.
