| 8.  Valley-fold the lower half upward a little less than 1/3.   If I fold at exactly at 1/3, then rose becomes fat and short.   If I fold at close to 1/4, then rose becomes skinny and too tall.   If you experiment with it, then you will know what I am saying.   I found that a little less than 1/3 would be an optimal folding position. |
