Primary textile structures have been described by different criteria, like by the number of (sets of) threads and draqwings as in Emery and by the topological properties of a repeating cell by Grishanov et al. For cataloging a large number of patterns Velasquez et al used a matrix containing the identifier of the thread (warp or weft) above the other in the weave. This was insufficient for textiles of several layers and its extension to a 3D tensor is complicated for the consistency check and insufficient to follow the threads in the presence of supplementary warps, even without crossed warps. With crossed and twined warps and wefts or non-woven structures (knitting, sprang etc) something more general is needed. As opposed to taking the warps and the wefts as objects like in the matrix representation, we propose a representation of the textile with the (top view) intersections of two threads as basic objects. The intersections have pointers to their four neighbouring intersections (along the threads) and a few more fields for position, which of the threads crosses above and the other end of the four links (crossing and link). We shall expose this representation, the necessary operations of the textile editor and the computing needed to determine the 2D coordinates of the crossings and the rendering of the textile. The editor will be demonstrated
