These mats, table centres, coasters and trivets are handmade by Gillian (the manager) using cotton cord/rope. The mats vary slightly as the rope/cord that is used is not the same every time she buys it so each piece is not perfect or exactly the same as the next.
If you are looking for a mat of a specific size, please contact Gillian shop@thenavigationcentre.com.au and she will be only too happy to send you a quote.
