Seagrass is available as a twisted grass rope or a flat-surfaced reed that resembles rush from the Sea Islands and is used in many folk art baskets, rugs, mats, placements and table runners. It is favoured by weaving enthusiasts because the seagrass begins as a green-coloured fibre that turns tan with age. Seagrass is easily dyed with fabric dye to take on any accent colour. The rope-textured seagrass presents a natural appearance and adds an interesting texture to any table. Make 30 by 45 cm (12 by 18 inch) place mats out of seagrass to add a touch of nature to any table.
Cut 24 pieces of seagrass rope 45 cm (18 inches) long and 68 pieces of seagrass 30 cm (12 inches) long.
Place the 45 cm (18 inches) seagrass pieces on a horizontal plane with 1.2 cm (1/2 inch) between pieces. Make sure the ends of each piece align to make an 27.5 by 45 cm (11 by 18 inch) rectangle.
Find the centre of the 45 cm (18 inches) pieces of seagrass. Weave one 30 cm (12 inches) seagrass piece through the 45 cm (18 inches) pieces at the centre mark, using an over/under weaving pattern. Leave 1.2 cm (1/2 inch) of each end of the 30 cm (12 inches) seagrass exposed past the 45 cm (18 inches) rectangle.
Weave one 30 cm (12 inches) seagrass pieces over/under on each side of the centre weaving. Start the weaving opposite of the first weave. For example, if you started the first weave going over the first 45 cm (18 inches) horizontal piece of seagrass, start the pieces on either side of that centre weave by going under the first 45 cm (18 inches) horizontal piece.
Continue weaving the length of the seagrass mat, alternating from side to side of the centre to keep the place mat squared. Always start the new weave opposite (over or under) the piece next it. Continue weaving the place mat until 1.2 cm (1/2 inch) of each 45 cm (18 inches) end is exposed. The finished place mat now has an edge, and you do not need to add a binding or hand weave a finished edge.
Use the same process to make a larger placement, table runner or rug. Change the lengths of the seagrass pieces to match the dimensions of the new rectangle.
