Undoing yarn, commonly known as "frogging," involves carefully unraveling your knitting or crocheting work to correct mistakes or repurpose the yarn. Start by removing your project from the needles or hook. Find the end of your yarn and gently begin to pull, unraveling your stitches. For knitted projects, it's easier to unravel row by row. If your yarn starts to kink, pause to untangle. Once completely unraveled, roll your yarn into a ball to prevent tangling. Frogging requires patience and care to avoid damaging the yarn, ensuring it can be reused for future projects.

To fix a leaking PVC pipe joint, start by turning off the water supply to prevent further leakage. Dry the area thoroughly. If the leak is small, apply PVC primer and cement over and around the joint. For larger leaks or damaged joints, you’ll need to replace the section. Cut out the damaged part with a hacksaw, ensuring the cuts are straight. Clean the ends of the good pipe and the inside of the new fittings. Apply PVC primer to these areas, followed by PVC cement. Quickly join the new section to the existing pipes, holding each joint firmly for a few seconds to ensure a secure bond. Allow it to cure for the recommended time before turning the water back on.
