Your warmest quilt would be wool batting (preferably old fashioned wool carded at the woolen mill), and tied. We make the ties loosely - don't pull the first knot tightly to keep the air in that area. If you've ever put insulation into a house, you know that you don't stuff in it. It needs to be kept loose to trap air. It's the air that is the insulation. The same happens to quilts. Machine quilted is not near as warm as tied because the layers are all smashed down and don't have any air in them.

Good point, mavis. Unfortunately I am not a big fan of tied quilts. I think I will go with WB + Wool. The quilting will be custom but not overly dense. That way I should have air-space. A plan has been conceived. I'm always happy when things get into gear.

I still favot stacking two quilts to having one super thick one. Easier to wash or dry clean, for one thing.

I think i would favor using two " lighter weight" quilts over one "very heave one" for a coupke of reasons.

I think it would be eazier to wash or dry clean a thinner quilt and "layering" gives a person more options temperature wise.

Good point, bear. I remember one of the craftsy teachers talking about layering half of a wool batting (she carefully pulled it apart) over another batting. I'm still waffling. Will decide when the time comes and my friend finishes the top. (I got "voluntold" for FMQ.)
