Warm & Plush, without a doubt (100% cotton, no scrim, no visible seeds). I'm getting the supplies to make my own suspension arm for my sewing table because it is also really heavy to have to be pushing & pulling through my machine to FMQ, but it feels really wonderful. I, too, love heavy quilts. I seriously want to steal my 3-year old niece's lap quilt away from her. :p

I only make crib & lap quilts, so I can't attest to how miserable it might be to try to FMQ a King quilt with this batting, but if you're willing to deal with the weight when quilting, that's what I'd recommend.

I made a cathedral window quilt with Hobbs warm and natural. This was heavy because of the top many layers. No problem with quilting.

I made a quilt using batiks for the top, a layer of W&N wool batting, a layer of flannel for batting, and then flannel for the backing. It is very heavy and very warm (delightful)!

I use W&N batting all the time and everyone says how heavy the quilts are...and they are even with just regular quilting cotton fabric. Add flannel as a backing and even heavier and warmer!

I just done a levi 10 minute quilt with one layer of batting and a cotton back and it is very heavy. I also have a levi quilt eith 2 layers of batting and it is even heavier.

I always thought that W&N was heavy compared to Hobbs 80/20. But then I have lived most of my life in So CA.

If she wants a heavy quilt, double the batt and then tie the quilt. It will go quicker and will be very warm.

Does she really like the weight or is it the warmth? I have been using a Hobbs Heirloom Wool batting and a Bamboo or Bamboo/Cotton batting together. It is warm, but not so much weight.

This is my suggestion, also. Quilter's Dream is my preferred batting overall. Various lofts according to the project. I used the Supreme loft in a quilt for my 7 YO grand-daughter and a flannel backing. I did FMQ on my home sewing machine. It was heavy and makes a nice warm quilt.

It is the weight more so than the warmth.
