Do you have your house row all sewn together into one strip? It looks like you have.
Are your log cabins still individual blocks?
I think, once you sew your log cabins together the houses and cabins will all match up beautifully. It always amazes me to see the difference in the rows when I start attaching the blocks to each other. Inches disappear!
If the above is not true then go with some "coping" strips! A coping strip is a quilter's best friend!
P.S. It's going to be a lovely quilt when you're finished.
