Cut out leaves from green felt. Stack leaves with smallest one on top, turn top leaf slightly and glue together. Cut tendril outline from green felt. Cut spiral lines to form tendril. Glue end at leaf base. [Tip: Use disappearing ink marking pen for transferring patterns.]
Cut face pieces from black craft foam or felt.
Attach leaves at neck and face pieces to t-shirt front with VELCRO® Brand Sticky Back coins and squares.
Put on t-shirt and stuff front and back with fiberfill. Tuck shirt in or secure bottom edge with belt. Rearrange fiberfill as needed to fill out t-shirt like a pumpkin. (May want to wear undershirt to avoid itching from fiberfill.)
After wearing, remove face, leaves, and VELCRO® Brand Sticky Back coins and squares to return t-shirt to original condition.
