Learn to Crochet - Stitch Variations
Most crochet stitch patterns, no matter how complex they seem, are made using combinations of basic stitches. Different effects can be created by small variations in the stitch making procedure or by varying the position and manner of inserting the hook into the fabric.
Note: Many patterns refer to certain groups of stitches in the instructions, but be careful—"bobble", "cluster", "shell", etc., may not mean the same thing from pattern to pattern. Always read the instructions to see what the designer means by a term!
