Help is on The Way!
Okay as much as I WISH I could help you with your specific questions about SVGs and your machine software, I just can't.
Why? I don't use my Silhouette ever. My mom does. I am a designer. Period.
I also don't own a Cricut. So I wouldn't be able to tell you ANYTHING about how to use their software or machine.
I love designing these SVG files and I have people that test and make sure my files work with Silhouette and Cricut machines. I trust them!
So if you're looking for assistance with your files or how to use them, I can only point you to some links:
Tried and true, the best thing you can do is Google your specific question. There are so many results out there and your problem could probably be solved with a video on YouTube or something like that. In fact, I use it to find these links below!
Our Facebook Group
I created a Facebook Group so people could share their projects using my SVG files or to ask questions about how to use these files and their machines. I am sure someone can answer your question. Join us here.
Error in Cricut Design Space - you cannot use the PDF file. You should use the other files, specifically the SVG file. Some people find that the error is the browser they are using. Cricut may only work with a specific browser so try multiple ones.
