TP to support a teapot handle has 3 major advantages: It's customizable. You can remove paper to make the interior curve of the handle smaller. You can squish the roll a little to get a more parabolic shape, in either direction. It's cheap and readily available. If there's no TP in your home, better stop reading and go get some. It compressed as the handle dries and shrinks. So, you won't crack your handle if you fail to remove the support at the exact moment the piece is firm enough.
Get the Look: Collections Inspired by LCDQ's Storytelling by Design- Composed of two simple cylindrical shapes of equal diameter, the No 2106 lever represents the height of functionalist design and geometric purity. The clean lines of the lever converge where the shank meets the leather wrapped handle and the circular rose. This handle can be used with traditional full-mortise locksets or manufactured for use with multi-point doors and tilt & turn windows. From Nanz.
