Key ideas in Crochet: From Chain to Keychain
- A slip knot acts as an adjustable anchor that needs to glide freely along the hook's shaft
- Over-tightening a slip knot locks the loop onto the hook, making it impossible to pull the next yarn loop through
- Both pencil grip and knife grip offer full control over the hook's head and motion
- Personal hand anatomy and wrist comfort should decide which grip you use, not rigid rules
- Switching between overhand (knife) and underhand (pencil) changes the angle and wrist strain of hook manipulation
- The dominant hand actively maneuvers and rotates the hook to catch and draw yarn
- The non-dominant hand acts as the tension brake, feeding yarn smoothly across the fingers
- Holding the base of the active stitch with non-dominant fingers keeps the loop stable so the hook can enter smoothly
- Each chain made by the hook establishes a single entry point for row one stitches
- The total number of chain loops directly fixes the starting width of your piece
- The stretch of the foundation chain dictates whether the bottom border can flex with the rest of the work
- Working the chain too tightly on the tip instead of the full hook shaft makes the chain loops smaller than row one stitches
- Tight foundation loops choke subsequent row stitches, forcing the bottom edge to curl inward
- Lifting the hook slightly to size each loop around the full shaft ensures loose, uniform chain stitches that lie flat
- Single crochet creates short, tightly locked stitches that yield a dense and firm fabric
- The hook draws yarn into compact stitches that resist stretching better than taller stitches
