I love that you can customize your own designs, colors etc! It's very easy for me as an amateur artist/designer (I've been making custom t-shirts since high school) because of how simple it is with this software!! The interface could be more intuitive but overall its pretty good at what they do - designing shirts in general & customized ones specifically :) If anyone wants something customizable or unique just go through their website first before purchasing anything from anywhere else cause there are so many options out here already available online which makes things easier than ever when choosing one over another design :).
