Prickings pinned on a double piece of cotton with tracing threads for making a part of a collar of needle lace

Pricking for a part of a collar of Venetian needle lace. The needle lace pattern is drawn in ink on light blue paper and holes are subsequently punched along the pattern lines. Through this 'pricking' and the double layer of cotton a tracing thread is sewn. When the needle lace stitches are made over and between the tracing threads the pricking and the cotton backing can be cut loose and removed. Then you are left with only needle lace, in this case a part of the collar which can then be processed with the other parts and the edge to a collar. The design of the collar was made by a person from Belgium who was interned in the First World War in camp 'Elisabeth-dorp' in Amersfoort. Mrs. van Nierop started making the collar and donated the unfinished parts to the Rijksmuseum as study material.
