I'm doing the 365 challenge quilt, quilt as you go. and quilted by hand or machine, I'd highly recommend Thermore batting.

How do I love thee, let me count the ways...
Originally designed for quilted clothes, it is super thin, very drapable, and I'm even splitting that in half!
Great for my little blocks, but this batt, halved, makes it a lot easier to machine quilt that bulk in a full size
It is SO light, a monster quilt would never be heavy!
(poly, guaranteed to not beard) so even thin you get a nice effect from the quilting.
I haven't needed to baste my blocks (6.5") for marking or quilting, cotton Sticks to it!
A good friend to my pocketbook, my 90"X 108" was under twenty dollars. Under ten dollars if you count that I'll be getting two quilts out of it
I'm also self facing the blocks bringing the backing around to the front, so no sashing...
The image is a baker's dozen blocks ...so you can see how thin and light these blocks are.
edited to add: Welcome butters, nice folk here, glad you've joined us
