Have you ever ordered wide backing from Marshall Dry Goods? I ordered it by the bundle and was very pleased with it.  Good prices and great selection.

Yes! I did too...wonderful idea!!

A tip I learned back when for determining light, medium, dark...take a pic in black and white. It will show you values quite well. Also the ruby beholder or other such thing helps, but the photo is the easiest :D HTH!

On your vacation trip in the fall you should go to their store.You would be amaze.They do have nice fabric and nice price.I was in IL Sat to visit my dad.Thought of you.

Thank you!

I was looking at their wide backs a few days ago but not sure of the quality as I have never ordered from them before. Thanks for the recommendation. 

This is going to be stunning - I love it already. 

Don't you like how happy Tula Pink's colors are!  I'm working with some of her fabrics on an EPP project called Tula Nova.  It's not as complex as the one you're doing, thankfully.  I wouldn't have the time or patience for that these days.  I admire you for tackling this.

I've been pretty pleased with connecting threads wide backings.  One of them (think it is called chambry) raveled a bit but otherwise nice.  And a couple of them have been as nice as very high end LQS.

That's what makes it a "forever" project.

Thanks for the recommendation I will check them out.
