Fusible Hobbs batting?
 

I was gifted queen fusible batting. When I took it out of the bag, it is so stiff. So if I use it, and I iron it both sides to backing and top, with it soften up?

I believe it will soften up when you wash the quilt after it is done. I think it dissolves. You could always check the website for hobbs or cut off a little piece and try washing it.

yep...it dissolves when washed. So the advice is not to use steam when you iron it on and from the comments, it looks like you need to iron both the top and backing on, one side at a time. The reviews I read, folks generally liked it and found it easier then pinning but did suggest, if you are doing a big quilt to pin just the edges after pressing the batting on if you are doing it on a sit down machine.

I really like that brand of fusible batting. I’ve never used that large of a fusible batting though. As others said, you iron down one side then iron the other side. Occasionally there’s been an issue, for me, of it not sticking very well. So then I needed to add some pins, especially around the edges. Mine softened up while I was quilting it actually.

I have never used this bat but is sounds like something I would like very much. Is it costly or close to the same price as something like the Hobbs 80/20 regular bat.?

I used it on a quilt and found it wasn’t for me. I think that it would have worked better if I had a space to lay the whole quilt out to iron. Trying to use my standard ironing board was frustrating. I even managed to scorch some of the fabric on my top, which required a repair job with new fabric. Even with frustration, the final result was fine. I just find using basting spray to be much easier.
