Two-needle cast on

   Have you experienced tight cuffs of your knitted socks?  Even though the cuff is made by ribbing, it would not stretch well...... If sock cuffs were too tight, you would not like to wear them-- that is very sad ending.  If I made an unwearable item (unexpectedly), I would cry, saying "Give me back the time!"  Making socks  takes time.  So, we would prefer to being happy when we see our completed works.  Cuff making is the very first step for us to take when we make socks (well, some people make socks from toe, though).   Two-needle cast on is a rescuer. This is a good technique for making a little stretchy cuffs for small items.
   As you can see in the pictures, simply use 2 needles when you cast on.  After casting on the number of stitches you need, remove one of the needles.  At this point, you can feel the stitches on the needle are loosely sitting on it.   This is very simple and effective technique to solve tight cuff problem.
