Siodach, your quilt is looking wonderful! I love your variety of pinks, the pink on the sides and your shade of sashing (which looks like a teal blue on my monitor). How brave of you to reduce block size (I'll walk miles out of my way to avoid math, LOL). I'm thinking of doing a 4x5 version also.
I've never worked with cool pink before; it just isn't a color I've gravitated to, but I am really enjoying the bright colors of this quilt.
