The video demonstrates how to create mockups of what a design will look like when cut out of patterned HTV. This can be a huge lifesaver and prevent you wasting a lot of patterned HTV because you will know ahead of time what you can expect the final product to look like.

I share how to create mockups in both Design Space and Inkscape. If you want to fast forward to the Inkscape method, go to timestamp 8:00.

Please note that you should not save with the clipping mask in Inkscape to import into Design Space. Instead, it is best to release the clipping mask and then just import the plain text or design into Design Space, which you will then mirror and cut out of the patterned HTV.
