PVC pipes, made from polyvinyl chloride, are a versatile and widely used type of plastic piping. Their popularity stems from their durability, resistance to corrosion and chemicals, low cost, and ease of installation. PVC pipes are primarily used for transporting water and wastewater in residential, commercial, and industrial settings. They come in various sizes and strengths, designated by different schedules that relate to wall thickness. Due to their non-biodegradable nature, there's growing interest in recycling and more sustainable alternatives in the industry. Nonetheless, their efficiency in plumbing, irrigation, and construction applications makes them an indispensable part of modern infrastructure.

When selecting yarn for amigurumi, the most popular choice is Cotton or Acrylic yarn due to their durability and stiffness, which helps the amigurumi hold its shape. Cotton yarn, being slightly heavier and smoother, offers a clean, defined stitch appearance, making it ideal for projects that require a neat finish. Acrylic, on the other hand, is softer and more forgiving, allowing for easier handling and making it a good option for beginners. Both types of yarn come in a wide range of colors, enabling creativity in designs. The weight of the yarn is also essential; most amigurumi projects are best suited to Light Worsted (DK) or Worsted weight yarn to achieve the right size and density without being overly bulky. Using a smaller hook size than recommended for the yarn can help to create tighter stitches, ensuring the filling doesn't show through and giving your amigurumi a smooth finish. Ultimately, the choice between Cotton and Acrylic yarn depends on personal preference and the desired look and feel of the finished project.
