As cute as those puzzle holders are my little ones will dump them all in a pile! Instead, put puzzles, or other toys that have their own little pieces in baggies so they don’t scatter all over the place/go missing. I think these are two gallon sized bags. I keep all our puzzles in a basket/bin. Each child can have a puzzle and we don’t bring out another one until it’s put away. I also contain marbles, magnetic doll pieces this way.
