Five Stars for these fabric loupes: very light, folds up very small, yet then sets up in a stable way on top of your snow crystal card.
You can get higher-power magnifiers, but they're heavy, bulky, and pricey.
Bonus application for this magnifier: works really well for checking out the fibers on your climbing skins!
(Seriously, the compare/contrast among different brands is interesting.)
