這是一支無需分層即可工作的筆。 It's a pen that can work without a layers.
素描筆是簡單的素描筆,具有更柔和的感覺。
您所需要的只是畫線,然後選擇顏色,無需圖層即可將其應用在草圖下方。

我第一次嘗試時有一些例子。
Sketch pen is simple sketch pen that have more pastel feel to it.
All you need is just draw line, then you choose color and without a layers it applies it under your sketch.

There some example on my first try .
