I Spy Quilts are often made from squares and rectangles, since those shapes are easy to fussy cut, but you'll also find I Spy quilts made with other patchwork shapes and quilt blocks.
Snowball quilt blocks are one popular choice for I Spy quilts, along with many other quilt designs.
You'll find an easy Snowball quilt on About.com Quilting (with examples of I Spy blocks) and several images of I Spy quilts on display in our quilting photo galleries -- see the links below.
