The shirts are perfect if you get the file in the right spot

My issue isn't necessarily all on the teamshirts. The shirts came out beautifully the only issue is the file wasn't in the right spot and couldn't go higher so the shirts came out great. Just wish the design was higher on the shirt than where it is now. But I 100% recommend this site
