Can someone explain what "I Spy" squares are? Thanks.

They are squares that have something that I child can look for in a game. I spy a dog, or cat, or bird. Unlimited things can qualify.

Here's a link to a my recent posting of a few I SPY quilts I have done for family and friends.

We've had I SPY swaps here on the board with 5 inch squares. I participated in three of them last year and have lots of different 5 inch squares now!

Anything with an identifiable picture can be considred an "I Spy", but usually they are medium scale prints.
