Can I upload a PDF into a comment on someone else's Instructable?
Hi there. I love this Instructable (http://www.instructables.com/id/TARDIS-Card-Bigger-on-the-inside/
) and while making it I ended up creating a PDF for the whole thing. I'd like to add this to the Instructable by uploading it into the comments, but I can't see a way to do that. I can upload a JPG but not a PDF... or am I missing something?
I've attached the PDF for reference (the help forum let me). Any help you could give me would be appreciated. Thanks!
