Make the brine by adding the water, vinegar, salt, sugar, and pickling spices to a small saucepan over medium-high heat. Bring to a boil then reduce to a simmer, stirring until the salt and sugar are dissolved. Set aside to cool slightly.
Add the cucumbers, dill, and garlic to 2 pint-sized jars or 1 quart-sized jar.
Pour the brine over the cucumbers. Seal and refrigerate, then serve as desired.
