A method for stitching thread to the wall of a tubular graft, comprising the steps of feeding thread from the outside of the graft through the graft wall to form a loop of thread inside the graft, passing thread through said loop, and pulling said loop closed to form a stitch. The thread which is passed through said loop may be a second loop of the same thread which has been fed through the wall of the graft, said second loop subsequently having a third loop of the same thread passed through it, in order to form a chain stitch in the graft wall. Alternatively, it may be a length of a second thread, which is subsequently passed through subsequent loops of the first thread which have been fed through the wall of the graft, in order to form a lock stitch in the graft wall.
