Is it possible that something simple like a rail fence could accomplish what you were thinking of?
Here is my favorite link to the rail fence, plus I copied the part where it talks about a woven pattern.
Just in case it is what you are thinking of....
Welcome to the board, by the way!!

Woven Effects
Staying with a 5 strip block, now grade from the outside to the center, either light to dark or dark to light results in these basic quilt blocks.
Again, in this rail fence quilt pattern design we set the blocks in horizontal rows and the results with light fabric on the outside...
...or with dark fabric...
Using hand dyed gradations will produce a subtler effect. So much so that you might consider having the horizontal rows in one color family and the vertical columns in another.
