Question about batting - flannel
I'm working on a quilt for my soon to be born grandbaby. I am using flannel as batting and backing. My problem is that I had to change the design of the quilt top to allow for a very crooked cut on a panel. I added two borders and wound up with a quilt top that is about 6" larger than the flannel that I bought for the batting. I have a piece of the same flannel from another project and can add it to the piece that I was to use for the batting. Will this make the quilt lumpy along that seam? Is there anything else that I should know before doing this? Or do I just need to make the 45 min to 1 hr drive each way and just buy another piece of flannel?
Thanks for all your help!!
