DIY Rhubarb Pavers
To make the pavers, take a simple concrete cast from rhubarb leaves.
Rhubarb leaves are a good choice for pavers because of their size.
As the pavers aren’t structural, use quick-set concrete, mixing it to a creamy consistency so it takes a detailed imprint from the thick and fibrous leaves.
Use tin snips to cut chicken wire mesh 30mm smaller all around than the leaves, embedding it in the concrete to reinforce the pavers.
Position a rhubarb leaf vein-side up on a flat surface covered in newspaper.
To make the paver cast, mix quick-set concrete to a creamy consistency, then spread it over the leaf to at least 20mm thick using a trowel.
Add chicken wire mesh cut to size and apply another 20mm layer of concrete.
