Yes. DOL LA VA is a round rattan piece 30 cm (12 in) across that its listing describes as both a placemat and a decorative charger plate. KA MON PAN is also rattan, a shallow round basket 33 cm (13 in) wide and 2 cm high. Our other round placemats are sold as charger plates too, in water hyacinth, sedge or banana leaf sheath, for the same woven look in a different fibre.
A charger sits under the dinner plate, so measure the dinner plates you will use and choose a piece wider than them. Ten of the round placemats are 30 cm (12 in) across, YA NI SA is 25 cm (10 in) and KA MON PAN is 33 cm (13 in) wide. Each product page lists its exact measurements, so compare them with your plates before you order.
THI PA NAN, KO RA WAT, KA RAN, JI RA PREE YA and YA NI SA are woven from water hyacinth. Lavin is sedge with an open weave border, and MON CHI TA is banana leaf sheath. The listings for KUL CHA, PI TI MON and NA RA DEE do not name a material, so check the photos and details on those product pages if the fibre matters to you.
The round placemat listings advise wiping each piece with a damp cloth and letting it air dry, and the DOL LA VA listing adds that it should be stored flat to keep its shape. Each piece is made by hand, so expect slight differences in size, colour and weave between pieces of the same design.
