An on-machine-seamable papermaker's fabric produced by modified endless weaving includes machine-direction (MD) and first cross-machine-direction (CD) yarns. The MD yarns weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. The MD and first CD yarns are interwoven with one another in a first weave pattern. The fabric also includes systems of second and third CD yarns. The second CD yarns are interwoven with the MD yarns along one of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a second weave pattern which may be different from the first weave pattern. Likewise, the third CD yarns are interwoven with the MD yarns along the other of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a third weave pattern which may be different from the first weave pattern. The second and third weave patterns may be the same as or different from one another. The second and third CD yarns may make the compressibility and permeability characteristics of the seam regions like those of the rest of the fabric, or may improve the stability, uniformity and orientation of the seaming loops at the two ends of the fabric.
