I recently made a twin log cabin and I can relate to the blocks getting a bit wonky. I squared the blocks up after a few rows, and again when all the rows were added. It's time consuming but the blocks were all trimmed to the same size. I kept check on the center square to make sure it was kept square, if not square the whole block gets off center.
I learned early on to square up each block in a quilt. When I made my first few quilts I thought since I had cut the pieces to size and sewed 1/4" seams the blocks all would come out the same size. Well, that's not the case so my quilts were bigger on one side than the other and the sides were wavy.
