How to carve borders in easel

Trying to create something like this: https://img0.etsystatic.com/042/0/8060608/il_570xN.655688034_o2yg.jpg

I design it in inkscape and import into easel. However, I cannot get the edge of the closed polylines to act like a border. Instead they only act as a solid that I can either cut the outside of or fill entirely, if that makes sense. Thanks all.

do you have the file i can help you.
