Thanks for the welcomes and for Prism99's reply. I think my wife's been using pure cotton batting so far but was hoping to get Fairfield's 60/40 which she saw recommended by a quilter in the States but I can't find it available over here. Both of those you mention are worth investigating for us. Do they work with machines?
Yesterday my wife that different fabrics require different battings and since she is being suppplied with fabric squares by a friend in the US that complicates matters. Can anyone comment on that. The whole thing is certainly confusing me.
