I was remaking an old comforter I had. I really liked the top fabric so remade it by taking apart(they had only tacked it together in very few places). I bought wool batting as people here on the QB were always talking about how warm it was. Well, it just looked too thin to me so I doubled it with Quilters Dream Puff. I quilted it on a longarm so no problems with that. But, I found it isn't warm enough and we had to add an old store bought comforter to get warm enough. I'm quite puzzled as I have had experience with a thin quilt(with poly batting) and it was plenty warm enough even though the bed had less blankets than we use at home. The few quilts I've made I've given away(made with fluffy poly batting) so don't know if poly is warmer than wool. The spacing of the quilting is an interesting aspect. The quilting is about 5" apart and the quilt does has have good definition but is that quilting too close and affecting the warmth factor?
