  Mazharimousavi and Halilsoy [1] recently proposed wormhole solutions in
$f(R)$-gravity that satisfy energy conditions but are unstable. We show here
that stability could still be achieved for thin-shell wormholes obtained by
gluing the wormholes in $f(R)$-gravity with the exterior Schwarzschild vacuum.
Using the new geometrical constraints from thin-shell "mass" and from external
"force" developed by Garcia, Lobo and Visser, we demarcate and analyze the
stability regions.
