We work specifically with sublimation apparel, from t-shirts to jackets and everything in-between. There are many companies offering sublimation or spot sub printing these days, but it takes a lot of experience, and know how to achieve the best print possible. We have traveled the world over to find the the right equipment and select the best fabrics.


We ensure smooth execution while transforming your ideas into one-of-a-kind garments. From costing and sampling through decorating and packaging we will walk you through the entire process of cut and sew apparel. We enjoy working exclusively with USA apparel manufacturers and even in our own backyard in the Carolinas.


You don’t have to cut and sew to start your own brand. We have a lot of exciting new apparel styles and fabrics in 2022 that are already stocked and ready to brand in less than 2 weeks. Some of our most popular brands we offer are Bella/Canvas, Next Level, Alternative, Richardson, Flexfit, to name a few.  From silk-screen printing, DTG (Direct to Garment Printing), sublimation, embroidery or bubble wrap (nah we are just kidding) we can print your logo on almost anything.
