I'm currently making a half-size test batch of these:

REFRIGERATOR PICKLES
7 c. cucumber slices
1 c. onion slices
2 Tbs. canning salt
2 c. sugar
1 c. vinegar (5%)
1 Tbs. celery seed
1 tsp. mustard seed

Combine cucumbers and onion in a large nonmetal container. Sprinkle with salt and let stand 4 hours. Rinse and drain.
Boil sugar, vinegar, and spices for 5 minutes. Cool mixture and pour over cucumbers and onions.
Keeps in refrigerator for several months.
