While briefcase straps are pretty durable, they do break occasionally, and then it helps to know how to make a briefcase strap. Making a briefcase strap is cheaper than buying a new briefcase, so it will save you money by making your briefcase last longer. Get a thick nylon strap, similar to a seat belt, to make a briefcase strap. Also, your sewing machine will need to be heavy-duty or industrial to sew the strap, because sewing something as thick as a nylon strap can damage a household machine. The new strap will be attached to the brackets holding the original strap and covered with a piece of leather or vinyl that matches the briefcase.
To make a briefcase strap, you will need:
- An eighteen-inch long by one-inch wide nylon strap (use a color that matches your briefcase)
- A six-inch long, 3/4-inch wide strip of hook and loop tape, adhesive-backed
- A heavy-duty sewing machine
- A five-inch long by four-inch wide rectangle of leather or vinyl in a color matching the briefcase
- A five-inch long strip of 3/4-inch wide hook and loop tape, adhesive-backed
- Nail polish remover
- Cotton swabs
- Fold the nylon strap into thirds, so the raw ends overlap. The folds should resemble the folds in a brochure.
- Place the six-inch piece of hook and loop tape between the overlapped ends. The hook and loop pieces of the tape should be stuck together for this. Peel the protective backing off of the adhesive and stick the still connected hook and loop tape to the strap in the same place you positioned it.
- Sew all the way around the hook and loop tape, about 1/8 of an inch from the tape's edge. The closer you get to the edge, the more secure your hook and loop tape will be.
- Dip a cotton swab in nail polish remover and wipe off any adhesive sticking to the needle, feed dogs or presser foot. Let dry while you prepare the leather strap cover. Repeat as needed and also when finished.
- Place the leather rectangle face down and fold each of the long, five-inch edges over 1/2 an inch. Peel the adhesive's backing off of the hook section of the hook and loop tape, and stick it over one folded edge.
- Choose a folded edge and sew across 1/4 of an inch from the edge to anchor the fold. This will be hidden when the strap cover is in place. Sew 1/8 of an inch from the edge of both of the five-inch long hook and loop strips.
- Open the folded nylon strap if it is not already open, and center it over the briefcase's handle assembly hardware. Feed the ends through the hardware, and close the overlapping hook and loop strips on the under-side of the strap.
- Position the strap cover over the nylon handle, and wrap it around with the hook and loop closure on the bottom. Press the hook and loop tape shut to secure the briefcase strap cover.
