One end of one of the straps should be placed at the bottom of the bib.
The edge of the strap should be pinned, basted, and sewed to the right
side of the bib with a running-stitch. The other long edge of the strap
should then be turned in one quarter of an inch and the side turned in
one inch. The strap should then be folded through the middle for its
entire length and the free side basted to the wrong side of the bib and
hemmed. The remaining edges of the strap should be overhanded together.
The other strap should be sewn to the other side of the bib in the same
way.
