First, layer the finished fabric on a long table. Then cut according to the established plan. This basic plan involves calculating the number of sheets, quilt covers, and pillowcases to cut and the sizes they will need. Here, faults are also deleted or flagged.
For bedding, especially duvet covers and pillowcases, it is especially important that the top and bottom are cut from the same batch. If the product is from a different batch, the two fabrics may have shrunk differently, or one fabric may be slightly skewed than the other. This means that when the duvet cover or pillowcase is washed, the shape loses shape as different parts shrink.
Finally, it is especially important to cut the top and bottom from the same fabric direction. This is done because fabrics will always shrink more in the warp or machine direction when washed. This is because the fabric is constantly stretched and stretched at various stages of processing. So, when it's finally washed, the fabric relaxes and retracts in length. Weft or width also shrinks, but not to the extent that length shrinks. This is because it is not stretched to the same amount as the length.
So if the top of the pillowcase is cut lengthwise and the bottom is cut across, the top will shrink more and the cover will twist in the wash, making it harder to iron. The same happens with the duvet cover as it ends up with diagonal creases.
