Here is my newest Angel cutting. It is a little less than a one movie creation.
Thinking of something to cut onto a bifold heart is more difficult than cutting a mandala because there is more room to cover and use of space is not as symmetrical. You have to account for the inner shape of the heart. It is easy to leave too much open space, which renders lamination more risky. Attachments are also trickier. (Attachments are the points at which the main design is connected to the outside edge so it doesn't fall apart.) More has to be done with a blade. With a mandala (8 sided) or snowflake (6 sided) even small mistakes somehow come out looking interesting. Not so with bifolds, which look more like one-design papercuts. All this is in my mind when I am cutting bifolds.
