We have a Mario birthday party that’s just around the corner! We wanted to design shirts for both my boys, my husband, and me. Don’t you think it would be darling if the boys had shirts that read bros for life? Mom and Dad would have a super mom and super dad shirts that were appropriate for Super Mario Brothers. We did Mario-themed shirts here, but you could use the steps below to create any kind of shirt! We will show directions on how to create your own designs and how to make a shirt using a pre-made template or picture from the web.
