A knitting needle set holds your yarn loops (stitches) while you knit. Sizes matter: smaller for tight fabrics (fingernails), larger for chunky scarves. Materials: bamboo is forgiving and quiet, metal is fast but slippery (get coated versions).
Types: Straight for flat pieces like blankets, circular for everything (seamless socks/hats - best for beginners), DPNs for small rounds (advanced). Interchangeable sets mix-and-match sizes/cables - ultimate beginner winner for versatility without buying multiples.
Best for beginners: full interchangeable circular set. Realistic expectations: You'll knit basic scarves in weeks, but expect uneven edges at first - that's normal! 'Beginner-friendly' means easy stitch pickup, no sharp points, and a case so you don't lose sizes.
Marketing traps: 'Pro quality' sounds good but often has steep curves. Evaluate by reviews from 'first project' users, not experts. Check for 4.5+ stars with 1k+ ratings.
Common terms: Gauge = stitches per inch (learn later), Tension = how tight you knit (practice fixes it). Start with medium worsted yarn.
