Changing the Color of Multiple Threads
Demo videos for desktop computers and an iPad can be found at the bottom of the lesson.
If you want to change sections of the threading or treadling, instead of clicking on each of the boxes the easier method is to click and drag. Select a color, click on a single box in the threading or treadling and, without releasing your mouse button, drag the mouse across the squares until you have covered the section you want to change. Then you can release the mouse button. The colors will update immediately as you are dragging the mouse.
In this example, both warp and weft threads were changed to blue using the click-and-drag method.
