My two favorite brands are Winline and Quilter's Dream. I have tested them all in my own personal quilts.
Looking for everyday use? 80/20, poly or cotton. Want extra puff to show off quilting? Wool or poly. Bed spread for all-season use? Wool, hands down, but bamboo sure is nice in the summer and warmer climates. In search of dreamy drape and cuddle factor? Bamboo!
I carry some 6 oz precut batts. Inquire for pricing and availability. It has all of the same properties listed above as well as a nice puff to show off quilting.
I stock some Poly Select and Poly Deluxe in precut batts in various sizes. Inquire for pricing and availability.
I stock a handful of cotton precuts in the Select loft. Inquire for pricing and availability.
