Hobbs Heirloom 80/20 Wadding - King Size - 120" x 120"Hobbs Heirloom Premium 80 20 Cotton Blend. Heirloom Premium Cotton Blend is made from 80% long staple cotton fibres and 20% fine polyester. This combination of fibres creates a strong, longwearing batt and is very easy to handle. The batting is lightly needle punched and treated with a soft resin to provide stability to the fibres and prevent the polyester from bearding. This process makes Heirloom Cotton Blend Batting uniquely easy to quilt by hand.
