Having a proper lash set up is important, a set of drawers next to you with all the supplies you need at hand, a chair at the right height, the perfect lighting. All these make a big difference.
This is important, it helps make your job easier and ensures your photos look amazing.
Its easy to buy a cheap chair, but if your lashing all day you need comfort. A saddle chair with back support is good for posture and what is recommended to lash techs.
