Keep your cuppa hot! This is more than a cozy - it is a blanket, thanks to felting (fulling). This pattern fits a cup 3.74”/9.5cm in diameter; 4.92”/12.5cm tall. I purchased this particular cup on Amazon - GlowHi Innocence big double heat-resistant glass cup 16.8 oz with lid with handle (yes, it says 16.8 oz, but it comfortably holds 12 ozs).

Easy to make in an evening. Add embellishments to personalize.
