measuring the seam is not the best way to judge your seam alloowance. you need to measure the units sewn together to see if you are hitting it. I have dozens of 3.5" unfinished 9 patches I've sewen over the years to check seam allowance over the years on different machines. .
I cut 1.5" strips (pressed fabric, unpressed fabric grows when pressed after sewing), sew 3 strips together, slice into 1.5" strips again and make your 9 patch and press. If at that point you have an exact 3.5" square you seam allowance is on the sweet spot.

Reb, I will repeat--1\4 inch difference over a distance of 10 inches is hardly anything. Looking at the design, the only place where points MUST meet, is where 4 blocks come together to form that background diamond (or on-point square). Try sewing 4 blocks together. Use a long stitch because this is just a test. See how it goes.
To make your seam width just a tiny bit wider, move your needle a couple of clicks to the left.
