I have the centre part of my Orca Bay mystery sewn together. I made half of the number of blocks for each step, and did not sew any string blocks, so my version looks quite a bit different than Bonnie's. Also I didn't use her colour recommendation and went with the 3 Sisters Grace fabric line, which is the name of my quilt - "3 Sisters Grace".
The rows went together amazingly well and sewing the top together was fun using Bonnie's technique of "webbing".
I'm not sure how many border blocks I will need for this size of quilt, but plan to work on those tonight.
