Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

Cutting the fabric along the marked lines requires great precision. This is where the skill of the sewer comes into play. Using sharp scissors or rotary cutters, the fabric is cut carefully, making sure to follow the cutting lines exactly to avoid any discrepancies. Even a slight deviation can alter the fit and aesthetic, so attention to detail is paramount. After cutting, it is common practice to use notches and markings to indicate seam allowances, darts, and other important sewing details, further enhancing the accuracy of the garment assembly.
