Funny that you posted this. I have just recently taken an entire quilt top apart because I didn't like the 1 shade of blue that i had picked.
I put all the pieces away & yesterday decided to give it another shot. I decided to use a soft ivory with a tiny pattern in it for the replacement & like it so much better. I just decided that I was not going to waste any more time & my limited talent on a piece that I didn't like. Maybe that' s being "anal" but I am so much happier with the quilt top, now. I ended up having to resize the blocks that didn't have the blue in them but it went much faster than I thought & nothing got distorted from all that extra "ripping" & handling. For me, it was well worth all the extra work.
