Pattern Corrections & Tips

• Keep stitches tight (drop a hook size if stuffing shows).
• Sew parts firmly to withstand play or use as a charm.
• For a larger seahorse: use thicker yarn and a larger hook.
• Placement of nose, eyes, and mohawk can be adjusted for a unique look.
• Pipe cleaner ends should be bent down inside the tail so wire isn't exposed.
