I'm finishing off a quilt which was bequeathed to me by my late mum. The top is already made so I just need to attach wadding and backing and do the quilting. It's made from polycotton pieces so I suppose I will back it with polycotton too. What would be the best wadding to get? IIRC she always used polyester wadding but that was over 25 years ago. My personal preference would be for a cotton mix but need to know what would work best for this quilt. Thanks!
