I use my iphone to take a picture of the group of fabrics, then edit, and use the tonal, noir or mono views to see how the tones match up. I find that taking a picture somehow gives a better view anyway.

Thanks for the explanations!

Jenny recommends them...they sell them on the Missouri Quilt site

I have an app for my phone that works great. The name is Snapseed. You can take a picture in color than change the picture to black & white. Works great to see color contrast.

watch Missouri Star Quilt Co, she runs daily deals and she ran these for a daily deal and they were $8 I think, any way they weren't $20, my friend and I are taking ours to Paducah with us.

Retreat night with Joleene
 

I'm so excited I got to sew with Joleene last night. She showed us the value of the red glasses and I think I need one for my purse and one for my sewing room they work so well. Now to go shopping for fabric.

They sure are more fun then a piece of plastic film.
