How to Make and Sell Custom Knit Sweaters: 5 Steps

Step 1: Choose a Manufacturing Partner

Until recently, one of the biggest challenges with making custom knit garments was finding a quality manufacturing partner.

Historically, you could try to find your own manufacturing on platforms like Alibaba, but you’ll have to pre-pay for large quantities of inventory and take on all the production risk.

The future of knitwear is Fourthwall's cutting-edge jacquard knitting technology. It's your ticket to premium, on-demand knit sweaters with no upfront costs and no minimum order quantity (MOQ). This means you can design and sell with freedom.

Thanks to Fourthwall's partnership with Knitwise, you'll enjoy unmatched quality in needlework and stitching for your community.

On-demand production ensures that each piece is made to order, eliminating waste from unsold inventory.

Not only is selling on-demand easier to manage, but it's also a more sustainable option. Each product is made to order, so there's no waste from unsold inventory.

This makes it the perfect option for your knitwear line. This isn't just a trend; it's the future of knitwear commerce.

Step 2: Design Your Knit Sweater

After you've chosen your manufacturing partner, the next key step is to select your sweater design.

You can create a design from scratch or start from many beautiful knitting patterns and templates that Fourthwall provides to you as you're fashioning your knitwear brand:

If you have your own vision, you can work with a designer to sketch and upload any of your own sweater designs or patterns! If you've never designed custom knit products before, keep these constraints in mind for your patterns:

1. There's a limit of 4 yarn colors per product. We have 36 beautiful yarn colors available, but only 4 can be woven into any one product. Fourthwall's design tool will automatically reduce your image uploads to 4 colors, making your life easier!
2. The collar, cuffs, and bottom hem must be the same color. Both for design aesthetic and to ensure there are smooth seams, the neckline, cuffs, and bottom ribbing must be the same color.
3. Products are a cotton-polyester blend (55% cotton, 45% polyester). Using a blend ensures that products feel premium but are durable (the yarn and fabrics keep their shape across multiple wears)

In total, you can pick from 36 Pantone color swatches for your yarn:

If you’re uploading a custom design, here are our recommendations to get an amazing result:

• Use darker base colors. These are more visually appealing, since the color accent yarns pop and have a more premium effect.
• Make the sleeves unique. If you want a high-fashion knit, you can opt for asymmetric sleeve designs, which make this a unique and premium piece of apparel.‍

Step 3: Order Samples

Before launching, we recommend ordering a sample for two reasons: to promote your product and to ensure you're getting a product that you're proud of.

Fourthwall's platform makes ordering samples easy. Once you place an order, here's how the manufacturing process works:

1. The manufacturer receives your order. Once the knitter receives your order, they'll prepare the knitting machine to stitch your knitted garment to perfection
2. Production begins. On average, the process to sew your products takes 7-10 days.
3. Shipping.  Orders ship from China to destinations worldwide. This process can take 4-16 days, depending on the shipping priority.

Here’s an example of a promotional sample knit sweater:

Step 4: Sell Them On Demand

Once you're satisfied with the samples, it's time to sell. With Fourthwall, you can sell your custom knit sweaters on demand.

Selling your products is as simple as marking them as public in your Fourthwall dashboard and then promoting to your audience.

When a fan places an order, the manufacturer is ready to produce each on their industrial sewing machines in 7-10 days. Fans then have the option to choose from two shipping methods:

• Standard Shipping. This takes 12-16 days and on average costs ~$10.50 for a single item
• Rush Shipping. This takes 4-7 days and on average costs ~$25.50 for a single item

Step 5: Market Your Sweaters

Seasonality plays a significant role in sales. While ugly sweaters are usually only popular during the holiday season, many other products like knit cardigans, vests, and beanies are popular year-round!

That's why it's important to keep the season in mind when deciding on your marketing campaign. Regardless of the products that you're selling, here are the promotional techniques that work best:

1. Create a TikTok, Reel, or Short about your custom knit. Be sure to show off the process from design to sample to product
2. Create a YouTube video about your new knitwear. Tell the story of why you're proud of it
3. Promote it on your live streams
4. Use Instagram or Facebook stories to showcase your knitwear and involve your community in the process

You can further boost sales by using features like Twitch Gifting or following many other eCommerce best practices.

FAQ: Designing and Selling Custom Knit Sweaters

What are custom knit sweaters?

Custom knit sweaters are garments made with yarn stitched directly into the fabric, rather than printed on top. 

This method allows creators to design fully custom patterns, colors, and textures for sweaters, cardigans, vests, and other knitwear.

How do custom knit sweaters differ from printed apparel?

Unlike print-based apparel like hoodies or shirts, knit sweaters are created by stitching the design into the garment itself. 

This results in higher durability, richer texture, and a more premium look and feel.

Can I sell custom knit sweaters without buying inventory?

Yes. With Fourthwall’s on-demand manufacturing, custom sweaters are made to order with no upfront costs or minimum order quantities. 

Each garment is produced only after a customer places an order, eliminating inventory risk.

What materials are used in custom knit sweaters?

Most custom knit sweaters are made from a cotton-polyester blend designed for durability and comfort. 

While traditional knits may use wool, cashmere, or acrylic, Fourthwall’s yarn blend ensures shape retention and easy care.
