Creating designs for hoodies and sweaters in Photoshop, we came across the idea to use the look of transparency in Adobe Photoshop or other graphics software as part of the actual knitsweater design.
Transparent areas in photoshop are usually checkered in light grey and white.
Using this background together with a cropped stock image gives a nice transparent effect. Please note the preview is rather low res, the actual knit sweater does look better, although only 4 colors can be used at a time.
You can use or rebuild this effect for your custom sweater design. Upload a partly transparent image in the Online Designer, and flood fill / tile the background with a two color clipart. Set the colors of the clipart to light grey and white.
When aligned correctly, image will merge with the background. If there is a 5th color in the image, replace / fill it with a pattern, and use colors that already exist.
Knitted with your custom design and no minimum order quantity, Wildemasche is the one stop source for custom knitwear. See all sweater specs here, and choose between fine knit cotton and regular knit acrylic sweater.
