Grab any Urban Threads design you think would look neat-o on a shirt. I like the heraldic crests because they fit nicely on tees. Not surprisingly, because I designed them to fit nicely on tees. I’m clever like that.
To guarantee proper placement, I’d recommend printing out your design to help with alignment. (Most embroidery software can print, and if you need some, check out www.Embird.com.) Measure the width of your T-shirt, and the width of your design, and make sure it’s centered in the middle. If your tee has any useful features, like a v-neck that helps you find the center, go ahead and use those too.
A word of caution before you start stitching away. Some nice stretchy thin tees might be just a bit too thin to embroider on. Detailed designs, such as this crest, might begin to punch through the fabric. If you have a super thin tee, I’d recommend using a lighter design, like a scribble. They work quite well.
