The video lessons show you how to replicate the projects, so no, they are not included. They are also not SVG files, they are Design Space projects. Design Space doesn't let you save your projects as SVG files. :)
Absolutely! Just "Flatten" it in Design Space using the button at the bottom of the layers panel to turn it into a print-then cut. You could flatten the whole thing so it will print as one image, or just the top layer.
I made a multi-layered card that is in DS - I think it was 6 layers - it was too thick to put in the post - I am in the U.S. and I needed to mail it to Canada - it was too costly, yet I really like the card - I think I will do it as a print then cut and just cut the top layer and glue it down - I am making a wedding card with raised flowers and they want $15.00 for postage - I have to come up with a way to bring the cost down - I don’t mind if it is $3. or $4. but $15. is way too much
