Cotton generally takes dye better than polyester due to its natural fiber structure. Cotton fibers have microscopic pores that readily absorb water-based dyes, allowing for vibrant and lasting coloration. Polyester, on the other hand, is a synthetic fiber with a smooth surface that resists water and does not absorb dyes as effectively. To dye polyester, disperse dyes or special processes like heat setting are required, which can be less effective and more complex compared to dyeing cotton. For deep, rich colors and consistent results, cotton is often the preferred choice.

In knitting and crochet, the term "yarn tail" refers to the loose ends of yarn that remain after casting on or starting a new skein. Determining whether the yarn tail should be on the right side (RS) or the wrong side (WS) of your work depends largely on the context and personal preference. When casting on, many knitters and crocheters prefer to have the yarn tail on the WS, as this makes it easier to weave in later without being visible. However, in certain techniques like intarsia or colorwork, having the yarn tail on the RS can be beneficial, as it allows for neater color changes and prevents unwanted tension issues. Regardless of where you start, always ensure there's enough yarn to securely weave in the tail later, typically at least six inches.

A gel base coat is a foundational layer applied during a gel manicure or pedicure before the application of gel color. Its primary purpose is to bond the natural nail plate and the gel color, providing a smooth surface for color application and enhancing the durability of the manicure. The base coat is cured under a UV or LED lamp to harden it, making it an essential step for ensuring the longevity of gel nail treatments. It also helps to protect the natural nails from staining and can improve the overall health of the nail by preventing breakage and splits. Using a quality gel base coat is key to achieving a professional-looking, long-lasting gel nail application.
