Shannon has done some really cool pixelated quilts. She starts with a simple image of an object: a pear, a heart, and uses the geometric app on her iPad for creating the pixelated image. She then creates the final quilt with squares, half square triangles, or quarter square circles or drunkards path blocks.
Here's Shannon's Pear from the 2 + 1 color challenge hanging at Sisters Outdoor Quilt Show last July
Here's Shannon's pixelated Heart. She made this for a February pink color challenge for the Mt Bachelor Quilters' Guild.
