Table topper question.
 

I don’t see why it wouldn’t work. Not sure why you want to double it up, I’ve used flannel many times as the ( batting) in table runners and placemats, but have never used more than one layer. Just prewash the flannel so it doesn’t shrink/ distort the runner.

Ckcowl, Thank you so much. I had totally forgotten to wash and dry it. Duh! I will do that now and use only one layer. My thought was whether or not it would be too thin for one layer.

Just be sure to wash it/dry it twice before using it. Then I think it will be fine.

I'm another who likes flannelette as batting for runners and mini-quilts.
Yes, definitely, make sure you hot wash and hot dry to shrink it well.
Actually, I usually do it at least two times.
One or two layers, just depending on what I am wanting for my finished quilt.
Flannelette can also be quite nice in a bed quilt, if you want one a little lighter.
Yet it can still be nice and cozy, with a lovely drape. I consider mine as a "summer quilt".

For your runners .... one layer is enough to do the job.
However, if you are wanting more padding for protection from heat or mositure, then more layers.

It really depends on how thick and bulky you want your finished quilt to be.
Also, there are different flannel weights to factor in. And how much quilting you will do.

Perhaps the best thing to do would be .....
..... to make your first with one layer, and see if you are pleased.
Then decide if the next should have two layers, or you stick with the one for it too.

Good Luck!
A great time to try out lots of different quilt patterns!

Cream-colored flannel also makes a great design wall cover.

I washed and dried the flannel and then used two layers in it. I will launder the finished toppernafternindonthe finding and see how I like it. Thank you for your advice, it is always a help.

Oh but please do show us!! :):)

I found a thin, white baby blanket in Mother’s cedar chest and I suspicions it was mine. I’ve used it as batting for 3 table runners.

I think 1 layer would work fine but like everyone else said you need to wash and dry it a couple of times. Also, I agree with "Lee in Richmond" that the flannel would work great for a design wall if you are in need of one and it sounds like you have plenty. I covered my design wall of foam core with flannel and it works good.

Flannel as batting
 

I agree. It’s a great light weight batting. I also prewash. It’s the only fabric I prewash. Perfect for a runner or even a Denim or rag quilt you want a little lighter.

After washing and drying the flannel, starch and iron it. I do that to all the flannel I use in sewing. I took a very expensive workshop and we were instructed to starch and iron the flannel before cutting.

Onebyone what a great suggestion. I will use. More of the flannel and give that a try. My table toppers turned out wonderful so am really impressed with flannel lining.

QuiltE I wish I was better with doing pictures. I am a real novice with techie stuff.

Oh I know what you mean ..... I used to be able to post photos on here, then somewhere along the line the system changed and no matter what I try, it refuses to let me to do so! :(

All the same ... would love to see what you are making with your great score of batting/flannel!

Have fun making them ... and be sure to make one, just for you! :)

Using the flannelette sounds perfect for table runners, especially when placing dishes or glasses on them. I worry a little about the thicker runners causing a tip over of a beverage if not placed carefully on them.

I only use a single layer of flannel with anything for the table because I do not want the poof of batting. I use the tall wine glass test - does it tip when almost empty? I find that a cotton top, back and one layer of flannel has never been an issue.
