As an avid reader of this board and wanting to take advantage of the Joann's sale AND a newbie quilter, what should I buy to put (stuff) in between my front and back of my quilt? Advantages and disadvantages, please!

Warm and Natural Batting.

A lot depends on how you want your quilt to look. Loft will give you a fluffy look and cotton more of a flat look.

Warm and Natural batting is awesome.

I also use the poly/cotton blend by WN when available and love it as well. I tend to stay away from full poly as it is hard to machine quilt, but works great on the log arm.

i like cotton because i like the old fashioned wrinkly look

I usually use the high loft poly from Walmart for ones I want to be 'fluffy'. Other than that I'm currently using some from a round bolt that I have no idea what brand it is as I inherited it from a quilter who went into a nursing home.

Warm and natural

Mostly Warm & Natural. I love Quilters Dream, and did just get a good deal on that at Hancock's of Paducah w/free shipping, so I treated myself to that. Also bought a Hobb's 80/20 to try. I'm, hoping I like it, the price is a bit better than the others are.

Warm n natural white or natural color is my favorite. If I want a little more puffy, wool is great, but I don't know if they would have any wool or wool blends.

If you are hand quilting, don't use warm & natural, it's too tough. Don't ask me how I know..........:-)
