How to Add a Soft Lining to Marine Canvas & Vinyl

Item # X-HT-300333

A cover is meant to protect your boat, car and other vehicles from harmful UV rays, rain and other elements. But sometimes these durable cover fabrics can be a little rough and abrasive on the more sensitive surfaces of your vehicle, such as on clear vinyl window material, varnished wood, car and boat paint finishes, and other areas. Protect your delicate surfaces by adding a layer of soft fabric to the underside of your cover. Read our quick how-to blog and conquer this DIY!

Evolution® Block-It® is the ideal soft fabric to add a protective layer between your vehicle or boat and your cover. It’s designed with a four-layer construction, offering breathability, strength and incredible softness. It’s also easy to drape and sew. Best of all it doesn’t fray, so you can cut it to the size you need and you don’t have to worry about hemming.

First, get all your tools and supplies ready. For this DIY you'll need your existing cover on which you want to add the lining material. You'll also need the Evolution Block-It material, Seamstick Basting Tape, scissors, a sewing guide (optional), thread and sewing machine.

Use your existing cover and use it as a template to trace the Evolution material. Make sure to cut your Evolution liner smaller than the canvas cover as needed to accommodate for any snaps, zippers, grommets, etc. Use basting tape to adhere the liner to the underside of the cover to make sewing easier. Baste the liner to the cover and take time to make sure the Evolution liner is lying completely flat. You don’t want any wrinkles in the material. The darker gray side of the liner should be facing up from the underside of the cover, meaning the darker gray side should touch your vinyl window, boat or car.

Next, sew the Evolution Block-It liner to the canvas cover using a straight stitch. If you already have an existing seam line from a hem, you can sew on top of that line for a cleaner looking cover without multiple lines of stitching. Remember to reverse at the beginning and end of your sewing to lock your stitches in place. Trim away any excess lining fabric to make sure it doesn’t interfere with snaps, grommets or zippers.

That's all there is to it! Now you have a soft, protective lining on the inside of your cover. You don't have to worry about your canvas cover scratching or damaging vinyl windows, varnished wood or other sensitive surfaces.
