I was wondering if any of you use them, and if so do they make the job easier? I'm going nuts trying to get the purples right for my Jenny Beyer quilt, and am toying with the notion of buying and trying one.

I used to have a red one, it helped a lot with the "in-between" colors, Some prints are hard to tell.

Someone said that red and green pieces of cellophane would work just fine for this. Do you know if that's true, and do they even sell cellophane anymore? I haven't really seen any in years.

Use A green beer bottle for green, and cherry kool ade for red........try one color for each eye :wink: :roll: :roll: :roll:

The dollar stores sell sun glasses with colored lenses :D

wow, I've never seen this before. Thanks Steve! Please post if you use this and it works for you!

You can also use a red plastic report cover (not sure if they come in green). Any red or green that you can see through will work. Even a tail light.

I do find them useful, yes, particularly when planning monochromatic quilts.

I used the red ones mostly for colorwash quilts. They are helpful as long as you are not comparing red fabrics to other fabrics.

The easiest way I've found for working with value is to take a picture with your digital camera, download it and then convert it to black and white. You'll see immediately what your values are. I have the value reader and rarely use it. Another method that has been recommended is to squint your eyes and look at your colors. It kinda works for me but not as well as the computer.

LOL - back before personal computers and digital cameras, we used to place our fabrics on a photocopier and make prints in black and white !
