Pattern Correction & Tips

• Correction: If the cover-up feels too loose/tight, adjust panel width by changing your starting chain (always multiple of 4+2).
• Tip: Try on panel regularly before sewing and adding straps.
• Tip: Side slit is customizable in length; mark before sewing.
• Tip: For wider or thicker straps, add extra rows of sc to strap chains.
