I love your fabrics - and this quilt has been on my bucket list for a while. Personally, I like #2 - but #1 would be a close second. The reason that I put #2 as my first choice is that it has some depth as well as movement but it is visually different from the fabrics in the block. #3 is just too plain for me and #4's pattern is too symmetrical in contrast to the movement in the blocks. This all being said (lol) my guess is what ever you choose the quilt will look great. Big question - Which one do you like??
