DIY techniques, or "do-it-yourself" methods, involve creating or repairing items without professional help. These techniques can range from simple home repairs, like fixing a leaky faucet, to crafting projects, such as making your own furniture. The goal is to save money and personalize items according to individual preferences. Common DIY techniques include upcycling, where old materials are transformed into new products, and home improvement projects that enhance living spaces. Tools like screwdrivers, hammers, and paintbrushes are often used, making it accessible for anyone to start their own projects with minimal investment.
