Hello everyone
I belong to a Facebook group called UK Silhouette Cameo chums. Questions are often posed on there where sometimes the answer isn’t quite clear. Now I love a challenge. I will go away and work it out then make a short video of the answer if the written explanation is too complicated or long winded to write.
This question was asked: Is there a way of making just one line of a shape perforated? for folding?  Here is the result.
