The photo below shows how the back neck lace coordinates with the front panels. I think it works well. Isn't my Petrea pretty in pink?
My next decision: what to do with the sleeves. The pattern calls for bell sleeves with a lace border, but Amy Herzog told me to forgo the bell sleeves because the Madelinetosh Tosh Vintage isn't drapey enough. I'm know I'm going to make them elbow length. I just need to decide whether to include lace above the garter ribbing.
Last night I casted on for the other side . Full steam ahead - regardless of my hot and humid misery.
