I finally settled on a shawl pattern from the Spring/Summer 1977 edition of Good Housekeeping Needlecraft. There’s no picture of the magazine on the Internet that I can find, but the cover looks similar to a picture on Flickr. I’ll get a snapshot of my copy posted later on.
I’m halfway through the first part of the center panel and I really like the way the shawl is coming together. You make three circles and two oval shapes chained together in four rounds and then a mesh is crocheted around the motif.
The pattern is called the Doily Shawl and I’d rate the difficulty as advanced for the odd directions and construction. When I first saw the project photo, it reminded me of the Wild Rose Shawl from the cover of the Winter 2007 Interweave Crochet, minus the flowers.
