Draw a face and clothes onto paper and then cut them out to be glued or stuck onto the roll with double-sided tape. An easier option is to draw straight onto the roll.
Stick a piece of doublesided tape at the top of the inside of the roll above the face. Cut strings of yarn and stick them to the tape to create hair.
Draw and cut out shoes from paper. Stick a piece of double-side tape to the bottom of the inside of the roll and stick down the ends of the shoes.
