Marine vinyl stands up to harsh sunlight and even harsher saltwater, making it the ideal material for boat cushions. You can purchase marine vinyl from most fabric stores or marine specialty stores. The vinyl has a shiny surface and a knitted fabric back and comes in many colors. The material is quite thick and slippery and requires special sewing techniques. If you want to make new cushions from marine vinyl or repair existing cushions, you'll need special equipment.
Things You'll Need
- Heavy-duty sewing machine
- Heavy-duty sewing machine needles
- Heavy-duty nylon thread
- Walking, Teflon or quilter's foot
- Tissue paper
Video of the Day
Place a piece of tissue paper underneath the vinyl before you begin to sew. The tissue gives the sewing machine's feed dogs something to grab onto and will help move the vinyl through the machine evenly.
Set the stitch length to between two and three stitches per inch. This will keep the thicker fabric from bunching.
Thread the bobbin and top needle with heavy-duty nylon thread. This thread is sturdier than cotton and will be less prone to break as you sew.
Sew with a walking, Teflon or quilter's foot. These special feet feed tough fabrics like vinyl through the feed dogs together.
Sew slowly and use one hand to gently pull the layers of vinyl under the needle and out the other side. Don't pull too hard or try to go too fast. Aim to work slowly but at an even pace.
Backstitch your seams to keep them from coming apart.
