I got 2 siicone ice cube trays exactly like the green ones pictured at Meijer's for less than $10. They are great for the camper, they release easily and are about 1 1/2" - 2" square..they are great for anything, but I use them for cocktails. I also have another one for freezing herbs in oil and after they are frozen I put them in ziploc bags in the freezer. I haven't made any soap yet but they will be perfect for that too. .☆´¯`•.¸¸. ི♥ྀ.
