CNC and manual quilt stitching allow you to create an additional internal profit center while providing additional design elements for your customer, like diamond pleated vinyl patterns on pleated marine vinyl upholstery.

In recent years in united states, quilt stitching on marine vinyl upholstery fabric has become a sought-after trend in the marine upholstery market. Originating in high-end boat interiors, it has been incorporated into marine products using marine grade vinyl fabric, offering a luxurious decorative touch using popular quilt designs like diamond quilted patters. Utilizing CNC and manual quilt stitching help increase internal profit and offer customers additional design options.

In the early days of this evolution, quilt stitching on quilted vinyl was a fairly easy process of basic straight-line channel stitching a layer of fabric to a foam layer and some backing layer. This process was easy and could be completed on the same sewing equipment we used to sew the cushions. The only talent required was being able to sew a straight line. The only real variable back then was the width of the channel.

Increasing options and expectations on quilted vinyl fabric

In the early days of quilt stitching and stitching diamond pleated marine vinyl patterns, it was fairly easy to create straight-line patterns by sewing a layer of fabric onto a foam layer and then onto a backing layer. This could be done easily with the same sewing equipment we use for cushions. The only talent needed was the ability to sew straight lines. The only variable at the time was how wide the channel needed.

Any pattern drawn or imagined can be sewn with the right automated CNC sewing equipment. With a little forethought and talent, many patterns can also be sewn on an ordinary walking foot sewing machine. CNC sewing equipment has become less expensive and opens the door to many other designs that cannot be achieved with standard sewing equipment. It’s either not a cost-effective use of your time to sew manually, or the patterns like double diamond stitched vinyl fabric are so complex they are not conducive to these sewing limitations. 

With today’s modern equipment, the next evolution is embedding embroidery with stitch patterns. You are starting to see this evolve on the automotive side, and we believe you will also see this element come into the marine market.

Contrasting the color of thread and welt allows you to add different design elements to your finished products.

Upholstery foam considerations

The thickness of the foam used as the backing is an element that can play a large part in a finished quilt design. The varying foam thickness is what will give depth to your finished product. At Canvas Designers Inc., we use everything from ¼-inch foam up to ¾-inch foam thicknesses. Most automotive products use ¼-inch foam, but the increased thickness of the foam can change the whole look of a design’s depth. We at canvasdesigners personally use ½-inch as our standard thickness and go down to 3/8-inch or ¼-inch only when we have a very small pattern and are looking to have a flatter look. All four foams we use have tricot backing already applied to them. 

If you attempt to do your quilt stitching, make sure you use a backing layer, or the quilting will look flat from the front side because the stitching will collapse the foam and not pull in the face material. There are even variables such as removing or collapsing foams in patterns to create even more 3D elements to the product. So, open your minds and feed your creativity by playing with your designs' foam depths and variables.

Three-dimensional foams, pattern variety, thread colors, and embedded embroidery offer fabricators a new palette of design elements to enhance their finished products.

Thread creativity on pleated vinyl fabric

An important element of your quilt design can be the thread portion of the job. This type of quilt stitching exposes the thread at the panel's surface. The size and color of the thread can contribute to the final look of your finished product. Using complementary or contrasting thread to the fabric's color allows you to achieve different design effects in your finished quilted marine vinyl products. 

As we have seen in the automotive industry, thread size can even play a part in the finished look. Everyone has seen sports cars with seats topstitched in bright fluorescent-colored large-diameter threads. Your equipment limitations may or may not let you vary the thread size, but remember that automotive trends typically show up in the marine industry, so be prepared for this element when considering future equipment needs.


Adding quilting to cushion surfaces lends an element of luxury to the finished products.

Equipment and talent upgrades

Canvas Designers has invested in equipment over time to align with the demands of the marine upholstery industry market regarding quilting stitching. We quickly realized that the throat limitation on our sewing machine made it very difficult to make any larger-sized patterns, so we invested in a 30-inch long-arm sewing machine to get more face fabric under the machine's throat. This helped tremendously for hand quilting and is still used extensively by our sewing staff for some of the basic channel and diamond requirements that are stitched. 

However, this method is limited and cannot be used in many intricate patterns we sew today, like diamond pleated marine vinyl. The more intricate patterns take extensive sewing talents and a lot of time to complete tasks using standard machines. Since we were already making custom comforters and bedspreads in our shop, we had a Gammill Statler® stitcher in our facility. Our Gammill was both a manual hand-guided machine and a computer-driven CNC machine. While it is typically used with lightweight thread to quilt bedding, we got it to sew the larger threads required for quilt stitching and do a decent job on the basic diamond patterns without much effort.

Anticipating market demand for marine grade vinyl fabric quilting

As demand for more intricate patterns and designs continued, we upgraded to our ZSK CNC embroidery machine. This is one of the few equipment options on the market that allows us to use both a heavy thread for the quilt stitching and a small thread for the embedded embroidery capability we were looking to add. Our machine is a 12-thread machine with six large threads and six embroidery threads that can be used simultaneously to create a design. This machine allows us to quilt stitch any pattern drawn or imagined, but unlike most other equipment, it also allows us to embed embroidery in our quilted pattern simultaneously. 


The embroidery machines in this market segment have a fixed head and a large hoop that moves the fabric in the pattern we are trying to achieve. Our machine has the largest sewing area available in the U.S. We can continuously sew a panel area of 52 by 54 inches with our ZSK and embed embroidery anywhere within this area. This capability gives us an infinite number of design elements that allow us to build unique and high-end upholstery products that many of our competitors cannot produce. It has also opened an opportunity to produce these panels for other shops and has allowed us to expand our workload to keep the machine busy doing our retail and wholesale work.

Quilt stitching can be found in products on the inside and outside of boats.

Upholstery designs change just like the fashion industry, but quilt stitching is the newest trend and one that will be here for a while, so jump on board and add some creativity to your next project. Whether you’re hand-guiding, outsourcing, or looking for your next equipment investment, this is an element of design that allows you to add tremendous value to your finished products.
