Most textile inks are too thick for a spray bottle. If you want a DIY solution, you may want to look at a thinner ink like what the Yudu uses. Suppose you can also water down whatever waterbased ink you have.

But the professional way to do it is to design your artwork and have a printer capable of doing 'all over printing' print them for you.

 

Do you know of a company that can do an allover print like this? My screen printer said it is a certain process that he doesn't do.
