LEA REDMOND

This book of twelve letters (ten prompted, two blank) makes it easy for children of many ages—from tween to adult—to show Dad how much they care. Once filled out, sealed, and postdated, the letters become handwritten time capsules to give to Dad for Father's Day, holidays, or milestone birthdays. When he breaks open the seals in the future, he will find a priceless keepsake.

Why not pop them in hiding spots for a treasure hunt to complete together?
