I prefer EASY!
I use a very light weight fusable interfacing, like what we sometimes used for garment making. Cut it into strips, 2-3" wide. Lay the edges of the batting together, use the IRON to fuse them together. No wrestling under the machine! When you have an available 40% off coupon, you can get yards of this for about $.60 per yard. Great stuff to have around.
I also use the light weight fusable interfacing as a stabilizer for t-shirt quilts - iron a piece bigger than what your final square will be, then trim shirt and fusable to the correct size.
