Window Sweaters is a free, open-source macOS customization application that decorates desktop windows with knitted borders. It adds colorful, sweater-inspired patterns around application windows without modifying their contents. Users can choose from predefined styles, including app-specific designs and coordinated zigzag patterns. The software includes handcrafted color schemes for dozens of popular applications. For other programs, it automatically generates complementary colors from their icons. Users can customize border width, stitch size, and individual application preferences. The application runs from the macOS menu bar and allows decorations to be paused or disabled. Compatible with macOS 13 and later, Window Sweaters provides a playful way to personalize desktop appearance.
