Then I add the dark mediums. I'm liking it better.
And finally with all of the darks in there the piece glows. I put this example up on the wall today for in progress shots, in 15 minutes or less. It definitely needs tweaking if I was going to sew it. All of these squares are from the 116 pc. kit on my blog-shop.
The point I am trying to make is that with a full range of value, the pattern of the quilt will show up. With fabrics in a "too close" value range, you will see none or very little pattern from a distance. To be sure you have values that separate and that will enhance each other, you need to step 8 feet away from the selection of bolts at the store, as if you were viewing the quilt from the doorway of the bedroom. Mix the bolts up in different arrangements to be sure you like each bolt against each other bolt.
