Would it be possible to retrieve just the skin stamp files separate from the rest of the course material?
Probably not, it all comes jumbled up together in a zip I think. Maybe with the new website that can be a possibility if it already isn't the case, to have only those files ready to download in that lesson in particular.
No worries! Thank you!
Once you download the course zip file, then extract the files, the skin stamp will be a separate file.
