You can create custom sweaters, vests, and cardigans from your dashboard. All knitwear is made with a 55% cotton and 45% polyester blend. This article covers design rules, yarn and color constraints, button options, and troubleshooting tips for getting the best results from your knitwear products. ## Design Rules and Yarn Color Limits Each knitwear product supports a maximum of four (4) yarn colors, including cuff and base colors. You can choose from 36 available yarn color swatches, but the system automatically reduces your uploaded artwork to 4 colors. Plan your design around this limit from the start. [Image: Hem and cuff knit color picker showing 36 yarn color swatches with brown selected] Key design rules: - **Four-color maximum.** All yarn colors in the product, including cuffs and base, count toward the four-color limit. The system reduces artwork to 4 colors automatically. - **Collar, cuffs, and hem must use the same yarn color.** This is a manufacturing requirement, not optional. - **Darker base colors produce better results.** Dark bases make accent yarns stand out and create a premium finish. Light bases tend to wash out foreground details. - **Sleeve patterns matter.** Asymmetric sleeves or contrasting patterns can elevate the final look. ## Button Color Options For knitwear products that require buttons, the button color is assigned automatically based on your trim color. You cannot manually select a button color. - Light trim color results in beige buttons - Dark trim color results in dark gray buttons ## How Jacquard Knitting Differs from Printing Fourthwall knitwear uses [jacquard knitting](https://fourthwall.com/blog/what-is-jacquard-knitting), not printing or dyeing. The pattern is stitched directly into the fabric. This means details are naturally simplified, fine lines become thicker, colors are limited to your four selected yarns, and the final product will look different from a printed garment mockup. If your design depends on micro-detail accuracy or photographic precision, jacquard knitwear may not be the right product type. Consider Direct-to-Garment (DTG) or Direct-to-Film (DTFx) printing for designs that need fine detail. ## My Uploaded Artwork Looks Tiny or Blurry in the Preview This is a common preview scaling issue. The mockup generator does not produce a one-to-one representation of the final knit output. To get the best preview results: - Upload a 300 DPI transparent PNG - Expect simplification from the four-color conversion - Evaluate overall composition, not pixel sharpness - If in doubt, submit a screenshot to [support@fourthwall.com](mailto:support@fourthwall.com) for sizing validation ## My Detailed Artwork Loses Thin Lines or Textures This is normal for jacquard knitting. Thread cannot reproduce extremely fine details. To work around this limitation: - Thicken line work in your design - Remove micro-details before uploading - Simplify textures to broader shapes - If preserving every detail is the priority, consider DTG or DTFx printing instead ## My Mockup Looks Perfect, but the Physical Sample Does Not Match Color shifts, scaling differences, texture distortion, and detail loss can all cause a physical sample to differ from the digital mockup. When a discrepancy is reported: - The support team reviews the issue and gathers needed details - The case is forwarded to Production for verification - Production decides on the appropriate resolution, which may include a remake, replacement, or another fix Contact [support@fourthwall.com](mailto:support@fourthwall.com) with your order number and a photo of the issue. ## My Design Overlaps with Part of the Sweater Pattern If you manually resize artwork to avoid overlap but the final product still shifts, this is usually caused by a small production sizing mismatch or a template rendering issue. Share the order number and a photo with [support@fourthwall.com](mailto:support@fourthwall.com). The support team will verify template behavior with the factory and follow up with a resolution. ## Best Practices for a High Success Rate To avoid rework and get the best outcomes from your knitwear designs: - Prioritize bold shapes over fine lines - Maximize contrast within the four-color limit - Mock up both large and small pattern scales for all-over styles - Run at least one sample before launching a campaign - Expect the knit process to soften sharp, crisp digital details
