When I was working on Dee’s onsie, I was frustrated by the lack of templates available, so I made my own. I took the Threadless t-shirt template, drew a baby onesie and then matched it to all the available colours on Threadless.
I thought I would make it available for download since many of the forums through which I searched didn’t have anything. This will help the other (million?) onesie designers.
(2.2MB zip file contains .eps, .ai and .pdf)
*Note: THIS IS NOT A THREADLESS TEMPLATE. It doesn’t necessarily match what they sell on the site. It’s just my template that allows me to test different colours of onesies.
*Update: The link above was broken for a bit during my site move. It should be working again. Please comment below if you have any issues.
