This website was listed on another website. I thought you might be interested.
By going to Judy Niemeyer's website, you can look at her quilt patterns change colors.
Click on a quilt and a new page opens. You click on the quilt picture in the upper left hand corner and a new large picture appears.
The colors of the quilts change! I thought it was really neat and if you haven't see them, you might want to check out this website.
