A woven pattern depends on consistent over-and-under crossings. Practise with two sets of three strips, focusing on segmentation and continuity. This is a 2D decoration without automatic material weaving or a specialised generator.

## Define the nine crossings first

Label three horizontal and three vertical strips and write the over/under rule for all nine crossings. Alternate adjacent crossings and verify from a checklist. Use two solid colours on an 800 by 800 pixel canvas with consistent widths, gaps and clear ends before adding decoration.

## Keep complete strips as source references

Create complete horizontal and vertical rectangles with useful names and retain hidden unsegmented references. Uniform stacking alone is not alternating weaving. Check widths and spacing before segmentation so every later correction has a complete source to compare against.

## Use local segments for alternating depth

Place local same-colour segments above crossings that require them, keeping each segment limited to its intended crossing and aligned with its parent strip. Use deliberate slight underlap where needed. Choose manageable paths or masks rather than requiring an automatic Boolean command. Verify every crossing as it is completed.

## Trace each strip for continuity

Trace each horizontal strip, then every vertical strip, checking all crossings against the same rule. Investigate unexpected colour changes or wrong copies. Continuity includes plausible passage through occlusion, not just aligned edges. Inspect plain colours first and keep visible entry/exit ends.

## Keep edge shading consistent

Add restrained edge shading with one light direction, grouping it with the relevant upper segment. It supports rather than defines the crossing rule. Reduce shading that makes strips seem cut apart. Validate an opaque construction before treating transparency as a separate experiment because blended colours can obscure strip identity.

## Test ownership by recolouring one strip

Recolour one strip in a copy and update all its local upper segments. Ordinary copies do not inherit parent identity automatically. Use names to find stale pieces, then restore the intended palette. This isolates style maintenance from crossing logic. Expand the crossing checklist before adding more strips.

## Inspect seams and narrow gaps after export

Save the segmented source and inspect crossing edges, ends and gaps in actual output on relevant backgrounds. If small crossings merge, increase spacing or reduce strip count before adding heavier shadows. Label the result as a 2D weaving illustration and retrace both directions in the final file.

## Repair one crossing at a time

Check the rule before correcting an apparent repeated over-crossing. Do not bring an entire strip forward and change other crossings unintentionally. For broken-looking bands, inspect alignment, colour and overlap width. Recheck neighbouring crossings and confirm the plain, unshaded construction already expresses the weave.
