The last break my kids had we did another puzzle by the same company and using Mod Podge saved the puzzle and then framed it. We did the same thing this time. One coat of Mod Podge on the front and one coat on the back is all it takes.
The entire time we worked on the puzzle the chairs from the dining room table were constantly in our way. I have three chairs on each side plus the two head chairs for a total of eight chairs around the table. I realized that the table looked so crowded with all of those chairs.
