Place sliced cucumbers in a colander and set it over a medium bowl. Sprinkle cucumbers with salt, and toss till sliced are coated with salt. Set aside to drain for an hour.

In a small bowl, combine vinegar with sugar and stir till dissolved.

Rinse the cucumbers a few times to remove the salt (they will still be salty). Pat cucumbers dry with a tea towel.

Divide cucumbers among clean, sanitized jars, and pour vinegar mixture till it covers the cucumbers. Store in the fridge for up to two weeks.
