I made enough blocks for two full size log cabins at once. You couldn't sew a straight quarter inch seam on that machine to save your life. I didn't precut the strips and used a sort of chain method. They came out on the crooked side so I slapped that big ol' 12 1/2 inch ruler and trimmed them all up nice and square. Unless I point it out to you, you can't tell the blocks were crooked at all.
