Jeandrig, do you cut your stripes to size before you start or do you string piece? I am trying to understand which part is curved. Do you press each seam after it's sewn or do you fingerpress? Are your seam allowances a consistent size? Are you careful to keep all the seams going the same direction? I found that I do better when I sew one block at a time rather than string piece. That way I always turn the block in the same direction and add the correct color (I don't do scrappy in log cabins).
