Certainly, recently discovered darning samplers consisting of six or twelve separate, one darn only pieces and joined together by lace now form a group. It's a somewhat unusual group.  The first one was worked by the Amsterdam girl Sofia Kip (1711-1783) in 1726 when she was 14 years old. This early and relatively simple example has four darns put together, one with a needle lace seam and two others with a plain seam. (See fig. 1) Fig. 1 Amsterdam darning sampler by Sofia Kip,
