Re-use plastic bottle tops to tightly seal food bags. Cut off wide-mouth plastic bottle top just at crest. save the cap. slip over bag opening. top toward the open end. Fold bag over bottle mouth. cap with re-used bottle top. easy to seal and pour!
For all my mason jar projects: An entire website with tons of different bottles or jars you can buy for thousands of different reasons. VERY inexpensive! Mason jars, cute little sauce bottles, medicine bottles.
