I use Warm & Natural cotton batting exclusively. As discussed here previously I have my own technique for making my quilt-as-you-go lap quilts. By using Warm & Natural cotton batting I have no puckers because the cotton batting sticks to the fabrics like Velcro! I love this “Velcro” property and therefore have been using their batting for as long as I can remember. I have a big roll that I cut off of and since I use it for all sizes of projects I have scraps too.
They go into table runners, and pillows and I also use them in stitchery projects as previously discussed too.
Today as I was working on yet another new project for Spring Quilt Market, I needed to piece a smidge onto my batting because my project grew a bit after I started. Not to worry though, my backing was big enough. My batting was just a bit short. So, I searched out a strip of batting and squared it up along with the end of the batting inside my quilt-to-be.
Here’s a tutorial to show you how:
Square up both pieces that you want to join.
and just zigzag stitched them together. I use the widest and longest stitch settings.
voila!
One piece of cotton batting! (I use cream color thread normally, but I wanted you to be able to see it here.)
I just finished my quilt by the way… Can’t wait to get it into pattern form so I can show all of you!
Until next time,
Susan
Quilting my way through life! 
Can’t wait to see the new pattern!
