Elle...I just love how you fussy cut the C7! The others look wonderful too. I remember that C4..it was a bit of a booger for me, it was hard to line up that center portion correctly. I swear that my new best friend when lining up the "units" to sew is that darn glue pen by sewline. Love the thing!! I wouldn't take much to put the white on the outside edges of C4..hope you find some in your stash
