About This Mod

The Christmas CAS Background is a creative, calm, festive backdrop that works well for both screenshots and everyday CAS use. The design leans on neutral tones, pairing soft beiges, muted greens, and minimal Christmas decor. This background is ideal for Simmers who prefer a minimal Christmas aesthetic rather than a heavily themed setup. Click on the link attached for more information on this background.
