JWR:
As many of you out there are doing, food storage will be key to survive the future. Mylar bags with food grade buckets are a great way of storing your food and I applaud the recent article "Sugar and Salt Storage. I would like to add my own little experience so that others may possibly benefit from it. Instead of using one 2×4 across the top of the bucket, use two. Gather the top of the mylar bag, then sandwich it between the two 2x4s, using C-clamps if needed. Then fold it over for sealing, using the extra surface of the added 2×4 for ironing, making it more stable. It worked well for me. – Joe Rotorhead
