Frequently Asked Questions
Does crochet use more yarn than knitting?
Yes, crochet typically uses about 30% more yarn than knitting for the same project size. This is because crochet stitches are taller and the fabric is generally thicker and less stretchy.
How much yarn do I need for a crochet blanket?
A throw blanket (50x60 in) in worsted weight double crochet needs about 2000-2500 yards. A baby blanket (30x36 in) needs about 1000-1400 yards. Full-size blankets need 4000-5000 yards.
What hook size should I use for worsted weight yarn?
Worsted weight yarn typically uses a 5.5-6.5mm hook (US I/9 to K/10.5). However, always check your yarn label for the recommended hook size and make a gauge swatch to verify your tension.
