A small hole in a waterproof jacket can let a lot of water soak through. Covering a small hole with a self-adhesive waterproof patch, made of ripstop tape, is faster than sewing a patch over the hole. Ripstop tape is available in stores that sell outdoors equipment because it is the same waterproof tape often used by campers for tent repairs. Ripstop tape comes in a variety of colours, so look for the colour that is the closest to the colour of your jacket.
Clean the area to be patched by scrubbing the clothes brush or soft cloth over the fabric to remove dust and larger bits of dirt.
If there are any frayed or hard spots sticking up from the hole, use the tip of the scissors to cut the rough spots off.
Measure the size of the hole with the ruler. Add 1 inch extra in diameter. This is the size you will be making the patch.
Use a pencil to trace the dimensions you measured on the tape. Cut the patch, rounding the corners.
Peel the backing off of the tape, centre the patch over the hole and press down firmly.
If the patch begins to peel after the jacket has been worn a few times, sew around the edges of the patch with a sewing machine to make a zigzag stitch for a basic seam finish. You may spray the needle with silicone to make it easier to sew through the adhesive. Coat the zigzag seam with seam sealer or waterproof spray or else the seam will leak.
