I have just finished cutting out my gazillion HSTs to put together a chevron quilt for my grandson. I'm doing it in white and 12 different patterned blues. Up to now I have been happily constructing my chevrons BUT grabbing my next bunch of HSTs with stripes I now realise that my stripes on one side of the chevron are vertical and on the other half, are horizontal! It's too late to do anything about it....all my material is cut and HSTs sewn and I'm guessing it won't be as obvious to my grandson but I could just kick myself! What basic error did I do when preparing my HSTs? How could I have avoided this?
