Bouncyfirm Lux is the new and improved version of the popular Bouncyfirm 160. It feels softer because the adhesive is applied to the smoother side. Furthermore, the fabric is run through a calender, making the adhesive and the fabric's surface even smoother.

A calender is a machine with heated rollers used to smooth fabrics, give them a sheen, or apply a certain texture. Let me know if you'd like a technical explanation!

Bouncyfirm is a firm yet flexible, iron-on, compact interlining. It doesn't wrinkle or hold creases like other products often do. You can roll your bag into a ball, and when you let go, it instantly springs back into shape. It's a great substitute for fleece and adds good firmness without the soft bulk of batting.

Bouncyfirm = I need a bag that is bouncy and stays upright.

• Width of the roll: 160 cm.

• Washable up to 40°C.
