Creating Stencil Bridges
This will show you how to add a stencil bridge to shapes in "Sure Cuts A Lot".
In this example we are using a letter O.
Choose the Rectangle shape from the Basic Shape in the Library window to add to the workspace.
If the Library window is not currently open, you can open it by choosing Library under the Window menu.
Move and resize the rectangle to where you want the stencil bridge
Choose the "Back Minus Front" option from the Path menu
And the result will look like the image shown below
