A method of seaming on-machine-seamable multiaxial papermaker's fabric to prevent yarn migration. The multiaxial fabric (22) is in the form of an endless loop flattened into two layers (40,42) along fold lines (38). CD yarns (28) are removed from the folds (38) to create ravel areas. This leaves the MD yarns (26) unbound in the ravel areas. Seam loops (56) are then formed from the unbound MD yarns (26) at the fold (38). A thin porous material (90) is sewn to the fabric at each fold (38). The porous material (90) binds the CD yarns along the edges of the ravel areas while allowing passage of the seam loops through the material. The laminate prevents migration of CD yarn tails into the seam area.
