A piece of stiff wire pressing against the trim around the pane was enough to keep it all in place:
Upsides: The foil is 100% opaque. It's easy to try and super cheap.
Downsides: It's ugly as sin on the inside if you don't have blinds or curtains covering it. It's kind of a big pain if you ever do want to quickly peek out of the window, but you'd have the same issue with opaque window tinting. Finally, direct sunlight is really, really
bright and if there's the slightest crack around the panel it can light up the entire room. My window takes direct sunlight in the morning and the tiny slivers of light making it around the edges of the panels were enough to show through the interlocking vinyl blinds I had covering everything; it's this last issue that finally drove me to remove the panels and cover the window with large seamless pieces of blackout material.
