That was nice and quiet Saturday afternoon. Of course, the jigsaw puzzle was enjoyable time for all family. My younger son, 3-year old boy, helped me and he was sticking blue and red tags onto the masks, when I’ve been holding them. Meantime, my older boy 7-year old, found really easy to put all the flat jigsaw puzzles together. My advice is to allow the glue on the puzzles to dry for longer than an hour. We had left it overnight and finished on the following day. The effect is awesome. My older son has really nice picture in his room now. Definitely I plan to purchase another mega blocks puzzle set.
