I bought my partner one and now I'm Design-A-Box inc, I'm also Design-A-Paper Background and Design-A-Shape lol! I'm also tech support apparently.
With any tool you need to practice and create some small items and waste a bit of paper, the trickiest part is getting the right cutting depth for the paper/card you are using, this is where testing comes in with each paper you buy and making notes with info like...
- Where you bought it
- The GSM or weight value (No two paper brands are the same even if they are the same GSM)
- Colour (I have found that coloured papers have their own characteristics from white papers)
- Test cuts, always do a test cut on a batch of paper (Don't use the small test cut i.e. the small square with a triangle in it, it's not big enough to get an accurate cut determination.
- Create a circle, triangle and square or rectangle, and add a dashed line to the square so it can be folded, Make the shapes about 2 inches (50mm) in size. This may seem like wasting paper but don't throw the shapes you have cut away keep it in a scrap box for smaller cuts or die stamping.
- The setting the cutter blade was on when it made a successful cut (less is more here, the blade only has to reach through the paper, any further is counterproductive
In the end, trial and error is the key.
Oh and learn how to use Illustrator or a vector app you feel comfortable with like Inkscape (free), it will give you a massive creative outlet.
Silhouette Studio (SD) is good but it's deliberately limited and if you want to be creative and more flexible, you will need to upgrade to Silhouette Studio Designer (SSD).
My experience of Silhouette is that it's all about marketing and upselling, you're buying into an ecosystem, that’s not a bad thing but personally, I like to be independent. My partner prefers 'Make The Cut' (MTC) but it really is a personal choice with regards to software, you can try it and see how you get on or stick with SD for a while and just play.
