such nice soft colors there in the last quilt. one block at a time girl. sometimes we all have blocks that dont measure up but it could work as an outside block perhaps.. or if you put in sashing put it on the bottom in a corner so you can pad the size of the sashing so it almost lines up. that is a 1/4 inch each side not much it might not be noticable. or you chock it up to experience and if you get the energy try that block just one more time this time watching how your size of cutting the pieces goes measure measure measure and when you sew your blocks/rows together measure them as you sew them together. are they 3.5" when sewn up? if not fix it right then. then sew it to the next one is that the correct measurement? so on a bit pain like BUT you can take out one small seam vs. a whole row.
