Last week we received some beautiful hand-me-down toys. One of them was a simple road-themed shape puzzle. Although my son is a little too old for this type of puzzle, I gave it to him because the vehicles were so nice. He really liked arranging the vehicles outside the puzzle on our coffee table, especially making the tow truck tow the others. We tried putting magnets on the backs so he could arrange them on the fridge instead and it worked out really well. He had a lot of fun with it and it only took a few minutes to make. A couple of the pieces were missing from the vintage puzzle, so I felt alright about repurposing the pieces.
We used a glue gun because it's so fast. Otherwise regular glue, or wood glue left overnight will work.
Craft stores, dollar stores and stationery stores all carry small magnets.
