[Additional:] Renovation work in progress Jan. 2017 has shown that several partitions incorporate vertical straw-rope panels. These tall panels were used as an alternative to woven wattle as a base for plasterwork, and were apparently restricted to Anglesey and Caernarfonshire. The straw rope seems to have been made from marram (dune) grass. Eurwyn Wiliam discusses this type of partition in 'The Welsh Cottage' (2010), pp. 218-20 (photo p. 220).

! I?ve seen a few of these panels before (notably at Gronant) and they seem to be restricted to Anglesey and Caernarfonshire. We describe them as vertical straw-rope panels and the straw rope seems to have been made from marram grass. Eurwyn discusses them in|The Welsh Cottage (2010), pp218-20 (photo p. 220).
