sprang

20 years of an eagle's flight

In principle, sprang may be regarded as a practical application of the fiber manipulation techniques used in the children's game known as cat's cradle.^[1] Sprang is made by preparing a set of warp threads either on a rectangular frame or between a pair of beams. The craftsperson then generates a fabric by interlinking the warp threads. Unlike most textile production techniques that add new rows at the end of completed rows, sprang works upon the center of a group of fibers and the material grows inward from both ends with symmetrical top and bottom halves. The craftsperson must maintain control of the center area or the structure unravels: most sprang worked upon has too many fibers to keep in hand, so rods or sticks maintain the appropriate fiber positions. The fiber manipulation itself is done by the craftsperson's fingers. Decorative patterns may be generated by regular variations in the fiber crossings. As crossings accumulate the craftsperson beats the material flat with a stick.^[2][3] Work continues with the material growing from both edges toward the middle until the center band becomes too tight to continue work.^[4] The completed fabric is either separated into two identical items or permanently secured at the middle to stabilize the contrary twists.^[3] In traditions where two halves of sprang are not severed by cutting, this center seam is a telltale sign of sprang manufacture.<sup>[3]
