Color Value tip
A few days ago, someone posted a link to a pair of glasses for seeing color value in your quilts.
Here's a trick you can use with something you might already be carrying with you:
If you have an iPhone or an Android phone, download the free app called "SnapSeed"
Take a photo of the fabrics with your phone.
Open Snapseed and select the photo you took
Tap "Black and White"
This will give you a really good idea of what the color values are.
I just tried it with the quilt I'm making for DH and I know now why I felt like the colors didn't "pop" enough. There's a light and 2 darks. The darks are too often next to each other.
