Plastic polymers are large, long-chain molecules made up of repeated smaller units called monomers. These synthetic materials are created through polymerization processes, where monomers are chemically bonded. Plastics have become ubiquitous due to their versatility, durability, and cost-effectiveness. They can be engineered with a wide range of properties, including flexibility, strength, and resistance to water and chemicals, making them suitable for countless applications – from packaging and construction to healthcare and textiles. There are two main types: thermoplastics, which can be melted and remolded multiple times, and thermosetting polymers, which cannot be reshaped after initial molding. Concerns about plastic pollution and sustainability have led to increased research into biodegradable and bio-based polymers.
Carrying yarn in colorwork, especially in knitting techniques like Fair Isle or intarsia, allows the creation of intricate patterns with multiple colors. The key is to maintain an even tension while ensuring the yarn not in use is neatly carried along the wrong side of the work or within the fabric. In Fair Isle knitting, yarns are typically carried across the back of the work, "catching" or "trapping" the carried yarn every few stitches to prevent long loops that can snag. This involves lightly twisting the two yarns around each other at intervals to secure the carried yarn to the wrong side of the fabric. For larger color blocks, as seen in intarsia, yarns are not carried across but picked up and dropped as needed, with careful attention to twisting yarns at color changes to prevent holes. Regardless of the method, practicing consistent tension and ensuring smooth joins between colors are crucial for a clean, professional look. Experimentation on swatches before starting a project can help refine these techniques.
PVC foam board, also known as cellular PVC, is a versatile material widely used in various industries due to its lightweight yet durable nature. It consists primarily of polyvinyl chloride (PVC), a synthetic plastic polymer. To create the foam structure, the PVC resin is blended with foaming agents, stabilizers, lubricants, and other additives that enhance specific properties like UV resistance, impact strength, or color stability. The mixture is then heated until it softens and expands, forming a consistent foam core. This process results in a rigid yet lightweight board that retains excellent dimensional stability and weather resistance, making it ideal for signage, graphic displays, furniture, and construction applications. Depending on the intended use, manufacturers can adjust the density and thickness of the boards.
