I'm trying to make some glyphs for an icon font. This one in particular has got me stumped. It's supposed to be a dollar bill going into an envelope. My only problem is I can't get the envelope to not show through the bill.

I'm using icomoon to convert the eventual svg file to a font set and I've come to understand that icomoon doesn't recognize fills, just strokes so I believe that puts the solution of filling the rectangle with white off the table.

Any ideas? Thanks in advance.

Splitting the path?
