I used to use W&N from JoAnne's but since there's not a store nearby I have gone online to look. I find Quilter's Dream 70/30 is similar to W&N in looks and quilts nicely for me at least. I try to buy by the roll as I hang it up over my cutting table. This last roll was king size so doubled over. Most of my quilts have been 105" and over so this works for me. I save my scraps and tape them together to make another piece the size I need using batting tape. Never have had any issues with the pieces coming apart after quilting.
Who ever has the sale at the time I need a new roll gets my business.
