Waterproof canvas is typically made from heavy-duty materials like cotton or polyester that are treated with waterproof or resistant coatings. These coatings give the fabric its waterproof properties, making it ideal for outdoor use. With this, some considerations have to be taken to ensure you are working with the fabric properly.

• Sewing machine: Ensure your sewing machine can handle heavy-duty fabrics. Not all waterproof canvas is a heavy duty quality though, so play around with what works with your machine!
• Presser Foot: A regular presser foot will work for lighter quality waterproof canvas, but it may be helpful to have a walking foot attachment to help evenly stitch the fabric.
• Needles: Use sharp, heavy-duty needles designed for sewing thick fabrics.
• Thread: Opt for high-quality polyester or nylon thread, as cotton thread may not withstand the elements as well.
• Cutting tools: Sharp scissors or a rotary cutter will make cutting through the thick canvas easier.
• Optional Seam sealant - Waterproof canvas can be prone to leaking through needle holes, so a seam sealant can help reinforce seams and prevent water penetration.
• Quilting Clips - Try to avoid using pins with waterproof canvas as these will put holes in your fabric. Opt for quilting clips to hold your pieces in place when sewing to avoid damaging your material.
• Prewash the fabric: While waterproof canvas is resistant to water, it's still a good idea to prewash the fabric to remove any dirt. Most likely it will not shrink, but it's great to remove any dirt or germs!
• Steer clear of ironing this fabric! Due to the water resistant coating, the iron will ruin or damage the material.

Mark your pattern: Use tailor's chalk to mark your pattern pieces accurately, as markers may be hard to see and pinning can damage the fabric.

Test out different techniques to determine what works best with your machine and fabric, but in general:

• Use a longer stitch length: A longer stitch length (around 3.5-4 mm) will help prevent puckering and ensure a secure seam.
• Backstitch at the beginning and end of seams to reinforce the edges. 
• Reduce bulk at seam allowances: Trim seam allowances and clip corners to reduce bulk, especially when sewing multiple layers of canvas together.

1. Finally you can add some seam sealant to your piece to help prevent water from going through the stitches!
