Depending on the garment, there will be locations you can design on the front, back and sides. The print areas will be shown as an orange box. Anything outside the box will not be printed (or embroidered).

The quality bar shows whether the image will print well - green is good!
The colours boxes show the image's default colours, which you can change by clicking on them.

Centre either horizontally or vertically (within orange design area)
