I'm trying to figure out how to say this. When I made a tumbler quilt, I started seeing the same thing - and then I realized the first row has to start with a set with the longer side on top and the next row has to start with the smaller side on top. I ended up having to take a set from the second row, split it and put one on each end of the second row. Hope this is clearer than mud.

Thank you all for your help. Now I think I know what what to do.( alot of quality time with my seam ripper)

Am I understanding that you did not sew the same length sides together when you sewed the pairs? Or did you sew the same size side without flipping? Maybe you could do something like a fan in the corners like https://myquiltprojects.wordpress.com/2018/02/ There is something Missouri Star calls a Chevron Tumbler where they are sewn so that the second row doesn't start with the opposite end on top.

In addition to the Tumbler shown above here are some other variations -

Thanks for all the links, beautiful quilts and ideas for the future.

Thanks printed this so I will have it the next time I need to post a pix.

I did mine in rows and then sewed the rows together.

Here's a photo of some unquilted Christmas mug rugs made of tumblers. To square them up, I cut off the sides slightly.

You will do just fine. Get it ripped out and once you are on your way you will have a beautiful quilt assembled. I have made 2 tumblers with different size blocks. Both are scrappy quilts. I put a white block at the end of each row and then cut the last row in half for a white border piece around the edge. I saved those pieces to be used on the next tumbler I find myself making. I can't wait to see what you come up with.
