Then you are back on plan.
Also, if all the blocks are like the one in the pic, it looks like you could square them to 7x7-1/2 and your borders could be 3/4 and 1/2", and the variance would be less obvious
This is what I would do. Another idea is to just run with the size they are now but keep them all oriented the same direction. Your quilt will be a little narrower (or shorter) than your original plan but it will still work.
