All the lines are clear, the unnecessary ones erased – ready to make the pattern pieces.
Here they are. Only one step left – make a specification sheet. Copy ALL the visible lines to a piece of paper and make all the stitch lines, brogues, etc + specifications on it, so your upper maker on the other side of the ocean will understand them.
