Beautiful, wildyard! I would suggest you audition the different border colors by pinning some fabric up under your top and taking photos. In the past I have used scrappy for an inner border when I didn't have enough of one fabric, so you might consider that if you want to try the green. I have seen the green and the medium blue used for the inner border on Quiltville (both looked good), but not the raspberry or dark blue.
Can anyone explain why we had to orient the partial block corner units differently on the half blocks, but they are all oriented the same on the first page of clue 9?
