After deciding what print on demand sites to review, we created the design in each of the sites. In all of them, except Spring Direct (which will get to in a minute) you have to create an account before purchasing your t-shirt. Two things to keep in mind:1
1. Redbubble has to verify your account before uploading your designs, so keep that in mind before using it.
2. Spring has two routes you can go through: Create a campaign and wait for it to be funded or use Spring Direct (the one we used), which lets you upload and buy your design without going through a campaign first.
Once we made our accounts, we proceded to create our design. For most of them, it was quite easy, with two exceptions:
With Spreadshirt we had an issue with the positioning of the design on the garment. The uploader wouldn’t recognize that our design was a transparent PNG file, hence having area without design. The automatic positioning was too small, but when we tried to make it bigger it showed an error saying that we had gone over the printing area.
