CROCHET HOOKS
Crochet hooks come in two styles with subtle differences and in most cases, will have little impact on your project. A standard pack of crochet hooks is perfect for beginners.
Crochet Hook Diagram
In-Line Crochet Hooks (aka Bates)
The head of a Bates hook has the same size, shape, and alignment as the shank (the part where your working stitch sits on the hook). This allows you to draw the hook back through each stitch in one straight line. This helps crochet evenly sized stitches and are less likely to snag while pulling it through loops of your project.
Tapered Crochet Hooks (Boye)
Boye hooks have a raised head and narrow throat, tapered at the end of with the hook. This can result in stitches that are too small or tight when formed close to the narrow tapered end.
