Fixing yarn depends on the problem at hand, such as untangling, joining broken strands, or reviving squished yarn. For untangling, patience is key; gently separate knots and work slowly to avoid tightening them. For broken yarn, a Russian join or a spit splice can seamlessly mend wool fibers, while a weaver's knot works for most types. To fluff up squished yarn, try soaking it in warm water with a bit of conditioner, then gently dry and re-skein. Always handle yarn gently to maintain its structure and appearance, and remember that practice improves your technique and patience when dealing with yarn mishaps.

To remove rust stains from PVC decking, you'll need a few household items and some elbow grease. Start by gently scrubbing the rust stain with a solution of warm water and mild dish soap using a soft-bristle brush, which can help loosen the rust without damaging the PVC surface. If the stain persists, apply a mixture of white vinegar and baking soda directly onto the rust spot and let it sit for several minutes before scrubbing again. For tougher stains, consider using a specialized PVC deck cleaner found at home improvement stores, following the manufacturer's instructions closely. Always test any cleaning solution on an inconspicuous area first to ensure it doesn't damage the deck. Rinse the area thoroughly with water after cleaning. Regular maintenance and immediate treatment of stains can keep your PVC decking looking new longer.
