Linda Peters Harvey's doll-sized pressing tools look just like the real human-sized ones! The top is made from a wool blend from her husband's old shirt and the bottom is made with cotton. Both sides are lined with muslin. She suggests using a curved needle to stitch the little opening! Excellent idea!
