Possible Quilt Layouts and Color Ideas

It is always fun trying out different color combinations and block placements with my Electric Quilt 8 software. These are all made with the same number of blocks. Look at all of the different results.

First I went with some fall colors. The second one is nice and scrappy, using darks and lights to give it a bit of sparkle. I decided to go with pastels for the third look and finally I went with a holiday scheme and the blocks are set on point.
