If you really don't want to use them in the quilt top you could make a table runner with them or a small wall hanging

I did think about trying to sew a new piece of red over the square.
Thanks for the suggestions! Not sure what I'll do just yet, I just ordered some red and more vintage style material to add to it, since I don't think I'll have enough. Anxious to get back at it!

I agree with "Pam S". Just continue making your blocks and scatter the first blocks with different centers around in your quilt. Keep moving on with your blocks b/c ripping out the center would be time consuming but it is possible.

I use different centers throughout my log cabins, so I would not be bothered by leaving them as-is. Also I think it would take me just about as long to replace the centers in the 6 blocks as to make 6 new blocks.

I have ripped centers from log cabin blocks. I use a very sharp scalpel blade and carefully "saw" through the stitches to remove center. I then cut a new center slightly larger than the original. I use fusible web to attach the new center to the block. Once the block is quilted, the quilting stitches will hold the new center in place.

So yes, it can be done.

I replaced these yellow blocks after the entire top was pieced. They used to be pink. I knew I wouldn't like the top if I didn't change them, so I carefully picked the pink ones out and replaced them with the yellow. I'm not sure about your log cabin, but I ended up using a Y Seam to get them back in, if I recall correctly.

If I was going to do it again, I would cut a new centre slightly larger than the old one, after backing it with something like Steam a Seam 2 Lite, fuse it directly over the one that was already there and then do a small buttonhole stitch around it with matching thread.

Sure you can but do it, carefully. Just this afternoon I had quilt top in the barn raising style lay out finished. So I thought. I found an error in in the second row from the top in the middle, Flipped squares. Fixed carefully. Hung it up on my quilt wall and............Found another pair of flipped squares. They are in the middle of the top and four rows in from the left side. Tomorrow. So, pick it out the center squares carefully, press and add the new little square to your log cabin. blocks. A bother for sure, but you will be pleased in the end and you only have 6 to correct. https://cdn.quiltingboard.com/images/smilies/smile.png

Applique a square over the center in the color you've chosen.

Every quilt I make there is always something that I change my mind about, and I have to remove it. I have tried to ignore them but then it becomes hard to even work on it - so I break down and make the change. So do what makes you happy and what will keep you sewing.

I like what you said. I'm also with" the leave them in" group.
