Sika-Design was established in 1942 by Ankjær Andreasen. Under the name "Jysk Siv og Halmkunst" (Jutish Reeds and Straw Art), Ankjær established a production of smaller wicker products which were made by home basket makers in Jutland, Denmark. Since there was a shortage of raw materials during the war, the production was based on free Danish raw materials, such as straw and reeds.
