Hi I'm from Surrey in the UK, thank you for letting me join, I have a query

Welcome. Like @Catllar as I read through I kept thinking minkie. I would skip the batting, really not needed, just causes more work. For the binding I suggest you consider lycra knit, like swimsuit or dancewear fabric. I've seen it used as binding on fleece garments to great advantage.

I would just tack the layers together in a tidy fashion.

Hello from me too. 

Great question by the way and I loved everyone's answers. I'm not a quilter but would love to learn.
