I didn't know what the 2nd item was...so here is a link for those who were uninformed like myself; it is a fusible batting.

It is spelled "Thermolam", a pellon product. I think since it's fusible, you wouldn't need to overquilt the center...& remember it's the air pockets that make it an insulator. Every stitching line is a perforation & pulls the layers tight together, reducing the insulating effect.
