Hi everyone! We have a small event coming up where the theme is a story within a story. So we're branching on to photo mosaics, photo malls, typography etc. Do you guys have any suggestions for good and preferably free photo mosaic softwares? Also, ones that produce hi-res as we're gonna print them. Also, we're trying to design t-shirts but don't have/aren't knowledgeable with Illustrator. Any recommended alternatives? It would greatly be appreciated. Thank you so much in advance!
