What kind of batting if any should I use for this wallhanging?
 

This is my first attempt at a wallhanging and I'm not sure if I need to put batting inside. Would it be a total disaster if I used some flannel I have as the batting? There will not be any quilting on it, at least I don't foresee doing any at this time. Do I need to do some quilting on it? As you can tell, I'm new at all of this, so any help would be greatly appreciated. Thanks so much!
Sorry it's sideways. Guess it was too long :)

That is cute and I think the flannel would work- it is to make it more firm , give it some body so it is not so limp :)

I see no probems using flannel, and if it is to be used as a wall quilt, and kind of thick, you could probably get by with no batting but it won't have the quilty look. I would use the flannel.

Thanks! Boy, that was a quick reply :)

The choice is entirely yours, but in my experience, wall pieces hang best with a stiff batting like Warm & Natural. It keeps them square and crisp looking and prevents them from getting droopy over time. Straight line stitching around the outside edge as well as around each white square should be enough if you decide to use W&N. If you go with flannel or nothing at all, be sure to use a hanging sleeve and not tabs or corners as your hanging mechanism. It will hang better with a sleeve to support it.

Have you ever thought of using fusible fleece? I use it all the time in small projects. It just just enough stiffness and it is fusible on one side and very easy to quilt through by hand or machine.

I personally would use a thin poly batting. Poly doesn't show fold marks and hangs better.

Hey Just Me, I don't think I realized that the poly batting doesn't show the folds. Thanks for the tip! I do like the stiffer bat for wall hangings and if there is no stitching it does droop though. I agree from experience, that there should be a little quilting on each square. Great wall hanging! Love the theme.

Personally I would use an iron on batting adhered to the backing. Don't know if they still sell it but I bought it small packages and used it for table runners. Then you could do an outline quilting on the blocks.

I would use a thin batting and QITD around the blocks and the edges to give it support as it hangs over the years.
