Soft Loft Fusible Stabilizer comes in a nice, big 60″pieces. You can choose one or two yards.
Fuse this stabilizer to the wrong side of the project fabric with a dry iron, using a press cloth. Take your time fusing as it requires steady, even heat. Once the stabilizer is adhered to the wrong side, you can also iron the fabric from the front to smooth and fuse it a bit more.
