Yess! For you any day. Once your piece of raffia is coming to an end insert the new piece of raffia and wrap a few wraps with the old raffia over the new piece. Just before the old one runs out start wrapping with the new one. This way you do not have any unsightly knots/joints.

Once the entire area you want to wrap is covered with raffia. split the end in two and continue wrapping with one of the two ends twice or so and then tie it off in a neat knot.

Hope that makes sense.
