Ugggghhhhhh, whilst undoing some of my seams yet again, sigh, I have noticed that I have inadvertently used 2 very different shades of white in my chevron quilt and it looks blinking awful. I have no choice but to rip out my rows and unpick about 25% of them and replace them. My question is...can I carefully undo the white sections of my chevron and replace with the "right" white, or do I have to completely disassemble the chevrons and re-make with the "right" white, or am I better off just chucking the "wrong" ones and start afresh? It seems a pity to discard the colour pieces in the chevrons let alone have to factor the purchasing of more fabric. What do you think I should do? Apart from sob quietly into my red wine and go and watch more cricket on the tellie? I really can't leave them as is.....the "wrong" white chevrons stand out like a boil and make the other chevrons white colour look dirty.
