Question ... they were stitched as is, would the points be cut off?
Meaning ... do you have a 1/4" seam allowance for each block, even though they are different sizes?
If so, what you could do would be to add a strip around each of the blocks, then trim all blocks to the same size, such as 14" or whatever size you wanted. I would keep those add on strips to about the same size as the strips in the log cabins. They'll be inconsistent but would blend in.
You didn't mention your log cabin blocks ... are they all finishing out at the same size?
Or do you have the same problem to deal with them too?
