I'm not sure I did it right. I wanted to use 1 gallon bags since I think it's a much more manageable size for my family. Anyway, I had seen a guy on youtube seal up 1 gallon bags with his foodsaver, which I thought was brilliant so I tried it. I couldn't get it to vacuum, which I found out later was because the Mylar is smooth instead of "quilted" like the Foodsaver bags. So....I filled the bags up more, almost to the top, and tried to get as much of the air out as I could and then put O2 absorbers in there, sealed it with my flat iron but they still look like they are "puffy" with air. Do I need to start over? Any ideas on how to get that Foodsaver to vacuum with the Mylar?
