Heavyweight sew-in stabilizer for projects that need to stand up on their own. Ultra Firm is 100% polyester with the body and stiffness of a thin board — the choice for millinery, costume armor, structured fabric bowls, and any project where the fabric needs to hold a shape with no help.

Ideal for:

Millinery: hat crowns, brims, and visors
Costume pieces, masks, and theatrical props
Structured fabric bowls and baskets
Book covers and journal construction
Decorative crafts needing rigid form

How to use: Sew-in only. Cut to shape and sandwich between fabric layers, or use as a single stabilizing layer. Can be machine or hand-sewn; a heavy needle is recommended.
