The Showgard #41 black mounts work well but only come in strips of 215 mm.
Below are a couple of options using the Showgard mounts. The first option is to cut the 215mm strips in half. While it is the least amount of waste on the mounts it does not cover the images.
The other option is to cut 120mm long leaving an 95mm drop. Looks very nice though.
Anyways, just sharing what I have fund for stamp mounts thus far. Please feel free to share other suggestions. I'm still mulling around ideas on the FDC album pages too.
Oups - I just noticed the bottom right image is peaking out.
