Since telling tone is sometimes hard and I don't own the red glasses, I have to adjust sometimes. I am working on a project that requires me to sew light and dark triangles together. I am using my cell phone camera on black and white or tonal to help me out. I have pics here in color and pics in tonal. You can see I have used the same light with both and a different dark, one solid and one print.
Tonal version makes it very obvious, as if I couldn't already tell with this one!! But look at my light, the color version shows reds and yellows on a pale blue background. The tonal version shows those reds and oranges as the same tone and the yellow as my light. I love using this method!!
I will take pics along the way so you can see what I get done. This is a very scrappy quilt using my blue and light scraps I posted about the other day. I am working on light blue/dark blue hour glasses right now. I need 174 of them which made for me cutting 696 triangles!!!
Back to the sewing!!!
