I lost count of the number of times I tried to straighten out the seams of the patches, but there was stretch in the fabrics I just didn't seem able to counteract. Irritating as it is, I have just accepted the slightly wonky back in favour of having a finished case on this occasion. Besides it doesn't look too bad from the front and it's even big enough to fit my 6.5" square ruler.
