I am doing a pinwheel quilt for DS for B'day It's teal purple and black. As I wass cutting the blocks I realized I only had about half the black I needed so I ordered more from connecting threads, So I am cutting out the rest of the black pieces and when I get done and I get my previously cut pieces I realize the the new stuff is really VERY dark navy! It said black on the web page and it looked black on my monitor. I am going to use it anyway...I will do the teal block with the navy It is really a very subtle difference and if he notices I will say I meant to do it that way :)
