Answer
When cutting the specimens from you sample fabric you need to line up the longest dimension with the warp or weft threads depending which direction specimens you are preparing then fray down the short end of the specimens, fold the specimen across the short end parallel to the threads in direction of the seam to be sewn (see section 9 of EN ISO 13936-1:2004). It is important that your seam is made parallel to the fabric weave. Note - you will get varying results when the seam is not parallel.
