Pinto describes the merticulous and water-tight construction of the bicker. Made in a range of sizes to form a nest, using alternating colours, typically the lighter sycamore and peat bog stained alder, once known as Scottish mahogany. The staves were 'feathered' along the edges (in this lot three times down each side) and then interlocked together at the grooved base, firmly bound in willow, which was then neatly 'laced'.
