Lomandra grows throughout the entire east coast of Australia and most commonly now used by councils to create green verges on the edge of roads and in council landscape.
When preparing to make a twinned dilly bag one can see the completed bag as you pluck each lomandra strand.
You harvest the fibres for your need
Choose central long clean leaves from the central growth of each bulb .
Hold the fibre between the tips of 4 fingers and the heel of your palm so this prevents the leaf from cutting your fingers.

These chosen leaves can be tugged / plucked or cut at their base with scissors or secatares.

The blades of lomandra are split and dried to desired width. The sun drying shrinks the fibre. These are then wet and twined. Dyes such as noni root, yellow rooted oyster plant and tumeric are bute natural dyes to use. The splitting of the leaf is critical to the finished baskets quality so try and split the width you like and be very consistant.
Drying a few days keeps the fibres tight as they can shrink considerably, and I like to dry and soak to exhaust the shrinking process.
