Pricking for making 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 along the pattern lines holes are subsequently pricked. In the next stage the pricking will be sewn onto a double layer of cotton. Subsequently tracing threads will be placed through the pricking and the double cotton underlayer that follow the lines of the needle lace pattern. When all needle lace stitches are made over and between these tracing threads the pricking and the cotton underlayer can be cut loose and removed. Then you only have needle lace left, 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 camp 'Elisabeth-dorp' in Amersfoort during the First World War. Mrs van Nierop started making the collar and donated the unfinished parts to the Rijksmuseum as study material.
