I have cut my blocks aand measured several times all blocks are the same square 8". When I join two blocks I am coming out that the bottom fabric ends up 1/8' inch shorter than the top fabric. How do I correct this. I have used my Janome 1/4" foot -- the seam is 1/4". With my Accufeed foot, the seam is 3/8" with the needle set as far right as it can go. The seam length is still 1/8" difference. IN eight blocks , that equals one inch.
Can anyone help me?
