How much does a tattoo needle cost?

Knitting needles can cost any where from $5-$20 depending on the brand, type, and size of needle and quality. For a beginner I would suggest getting the alluminum (also called turbo needles) needles, the yarn will slide more easily over the needles and make quicker progress of your work.

If you travel and want to knit then you can get bamboo or plastic needles, they should allow them on a plane.
