Does my dominant hand need to touch my non-dominant hand?
Yes, your dominant hand should lightly brush or touch the palm of your non-dominant hand as it performs the scooping motion. It shouldn't be a hard slap, just a gentle graze.
Can I use either hand to do the scooping?
You should always use your dominant hand for the moving, scooping part of the sign. Your non-dominant hand serves as the stationary base.
How is 'new' different from the sign for 'paper'?
While both signs use a similar base hand, 'paper' involves striking the palms together twice with a brushing motion. 'New' uses a distinct, single scooping motion with the dominant hand slightly cupped.
