batting preferences
I use several warm and natural/white is the one I use for most of my quilts. I also like the warm blend that I get from Joanns by the bolt and is available in 90" and 108/110 inches wide and about half the price. I use this a lot in donated quilts since it is the 50/50 blend and gives the best of both worlds. It also has a little more loft to it when it is quilted than warm and natural.
Bamboo and wool bat are excellent but price wise not an everyday use for me since I give many of my quilts as gifts and they are well used.
Nearly all my full size quilts are at least 90 wide so the 90 wide batting is not quite big enough to do one piece. So the wider width is a must for me.
