We gave each of our children a roll of Scotch tape in their Easter baskets. They loved it; it goes naturally with their love of coloring and crafting. Plus, it was preservation of my tape.
As my husband and I were buying it I told him, “Let’s not get the real good kind because I have no idea where they will stick it.”
Our 4 year old went through her whole roll in 3 days. Most of it was used on this wall.
