The batting I really love is Warm & Plush. It is about 50% thicker than Warm & Natural. It is very soft and is perfect for trapunto (which is what I have been using the free sample they sent me to work on) or for general quilting. It really show the details nicely. I haven't noticed any issues with seeing through it. JAF doesn't always have it in stock in their stores. Sometimes I see it in certain sizes, other times I don't. Their website seems to stock it regularly.
I am about to place an order for a roll of it to use in a few of my upcoming quilts -- one that's going to be in a show in August & another one that I designed myself and hope to submit for display at 2016 Quilt Week. I can't recommend it highly enough. Might be worth a try if you're like me & prefer to only work with all natural fibers.
