I crocheted all the pieces together with a simple chain stitch (not a single crochet--I wanted the resulting seam to lie flat.) You can see from the back view that I could have made the initial triangle smaller--it's a little wide for my shoulders. This is probably due to the weight of the sleeves. The yarn is heavy with a lot of drape--it's a linen/wool blend.
I joined the sides with panels in which I did some waist shaping with short rows.
I'm happy with it--just need some cooler weather so I can wear it! We are enjoying unseasonably warm temperatures these days--it's been in the high 20's and low 30's in the Okanagan...breaking some long standing weather records.
