Cotton and plant fibres

Fibre quality is only the start

Length and uniformity affect how cotton can be spun, while spinning method, twist, ply and evenness shape strength, smoothness and surface. Linen and regenerated plant-based fibres can behave differently again.

Plan for load and recovery

Plant-fibre fabrics often recover less than wool and become heavy when wet. Seams, hang and project structure therefore matter, especially in long garments or bags.

Measure the finished routine

Mark a generous swatch, record dimensions, then wash and dry it exactly as planned. Check shrinkage, growth, skew, hand and colour transfer before calculating the project.

Try this example

For a bag handle, mark a 20 cm span on a finished sample. Test it with the intended contents close to a supporting surface, then remove the load and let it rest. If the span remains 22 cm, it has retained 10% growth. Shortening the pattern alone does not fix poor recovery; compare a firmer structure or supported handle.
