Step 1 - Interleave the Threading

For this tutorial, open the Bethlehem Star Pattern from the prior step (Star-OvershotOriginal.wif). Note that if you are using your own Overshot Draft, be sure it does not have tabby treadles. In books, the tabby treadles are usually not included in the pick-by-pick treadling.

Change the tie-up to a straight 1-2-3-4 as shown below, with treadle 1 tied to shaft 1, treadle 2 to shaft 2, treadle 3 to shaft 3 and treadle 4 to shaft 4. Save this draft and name it Star-Step1.

Next, step is to interleave the threading with itself, shifting every other warp thread up by 2 shafts.

To understand Interleave Warp with a Shift of 2 and Wrap, think of taking the threading for the single layer overshot warp (as shown above) and adding one blank space after each warp thread. Fill in the blank spaces by taking the warp thread to the right and shifting it up 2 shafts; since Wrap is being used, if a thread on Shaft 3 is being shifted by two shafts, it will wrap around to Shaft 1; Similarly, a thread on Shaft 4 will be shifted to Shaft 2.

To interleave the threading from this draft with the same threading, that same draft either needs to be open in another window, or a copy of it opened.

To view and switch between currently open drafts, either use the "eye" in the upper right section of the screen, or use the Window function on the menu. Switching Between Open Weaving Designs

For this tutorial, we'll simply open the original draft (Star-OvershotOriginal.wif), and also have open the newly created Star-Step1.

With Star-Step1 open and in focus, select the Original Draft from the drop down, Change the Shift UP to a 2, be sure Wrap is checked, click Apply and Accept.

Included in the next steps are two versions of Step 2. One is an 8-treadle version that only involves pressing one treadle at a time; the second is a 6-treadle version that requires pressing more than one treadle at a time (skeleton tie-up).
