I love Hobbs fusible 80/20 batt! Things I do...I use a dry iron and a big surface to iron on. I iron the front and then the back. I put safety pins around the perimeter so I don’t lift the edge when moving the quilt. I quilt from the center out and may need to re-iron the back towards the edge(adjust pins) as needed. Washing will soften the quilt. If you densely quilt your quilt though, that will make it stiffer.
