Need advice, not lineing up properly
So I got this pattern from Love of Quilting and I checked the pattern and I checked fabric and stitching and its just not lining up! I feel like I'm going crazy. The final squares should be 3.5 but by triangle ones are 3.75 should I cut the larger triangle down? or cut the sides of the the other? I have no clue how to fix. Its creating major puckering issues.
