Interleave Warp

What It Does

Interleave Warp combines the threading from two open documents by alternating threads — one from your current draft, one from a source document, one from current, one from source, and so on. The result is a single threading that weaves together both patterns.

This is a powerful technique for creating complex multi-layer designs, combining different structures, or merging complementary threadings into a single draft.

The Dialog

Source Document

A dropdown listing all other open documents in TempoWeave. Select the document whose threading you want to interleave with your current draft.

You must have at least one other document open to use this feature.

Start at Thread

The warp position in your current draft where interleaving begins (1-based). Threads before this position are left unchanged.

Shaft Shift

An offset applied to the source threading's shaft assignments (0 to number of shafts available). This lets you place the source threading on different shafts than the current draft.

For example, if your current draft uses shafts 1–4 and you set a shaft shift of 4, the source threading's shafts are shifted to 5–8, keeping the two threadings on separate shaft groups.

Options

Copy thread colors — When checked, source threads bring their colors. When unchecked, interleaved threads get the current draft's default color.

Copy thread thickness — When checked, source threads bring their thickness values.

Repeat source through end — When checked, if the source threading is shorter than the current draft, it repeats from the beginning to fill the remaining space. When unchecked, source threads stop when the source data runs out.

Wrap shafts — When checked, shaft numbers that exceed the available shafts wrap around to the beginning. When unchecked, the shaft count may expand to accommodate the shifted source threading.

How It Works

Starting at the specified thread position, the operation alternates:

Current:  1  2  3  4  5  6
Source:   A  B  C  D  E  F
Result:   1  A  2  B  3  C  4  D  5  E  6  F

Each source thread's shaft assignment is increased by the shaft shift amount. If wrapping is enabled, shafts that exceed the maximum wrap around; otherwise, the shaft count grows to accommodate them.

The warp expands to hold all interleaved threads — the result has roughly twice as many threads as the longer of the two inputs.

How to Use It

1. Open both documents — your current draft and the source draft

2. Go to Design tab > Interleave Warp

3. Select the Source Document from the dropdown

4. Set the Start at Thread position

5. Set the Shaft Shift (typically half your total shaft count, to keep the two threadings on separate shafts)

6. Check the options you want (colors, thickness, repeat, wrap)

7. Click Apply

Step-by-Step Example: Double Weave Threading

You want to create a double weave threading from two separate drafts:

1. Open your top-layer draft (4 shafts, threaded on shafts 1–4)

2. Open your bottom-layer draft (4 shafts, threaded on shafts 1–4)

3. Go to Interleave Warp on the current (top-layer) document

4. Select the bottom-layer document as the source

5. Set Shaft Shift to 4 (source threads move to shafts 5–8)

6. Check Copy thread colors and Repeat source through end

7. Apply — the threading now alternates top and bottom layer threads on shafts 1–8

Step-by-Step Example: Combining Two Color Warps

You have two single-layer warps with different color arrangements and want to merge them:

1. Open both warps

2. Interleave with Shaft Shift 0 (both use the same shafts)

3. Check Copy thread colors

4. Apply — threads alternate between the two color arrangements

Tips

• Shaft shift for layers — Set the shaft shift equal to the number of shafts in your current draft to place the source on entirely separate shafts. This is the standard approach for double weave.

• Repeat for uneven lengths — If one draft is shorter, enable "Repeat source through end" to cycle the shorter threading.

• Expand vs. wrap — Wrapping keeps the shaft count fixed but folds the source back onto existing shafts. Not wrapping may increase your shaft count but keeps the two threadings fully separate.

• Undo works — Ctrl+Z reverts the interleave.

• Save first — Since interleaving significantly changes your threading, save your draft before applying.
