Thank you all very much for the compliments. The pattern I used is from Laundry Basket Quilts, and it's called "Hawaiian Delight". I think it's still available on their website. Electric Quilt also has several pineapple blocks in their programs.
The logs are 1" wide finished. I started with an assortment of quarter yards and cut them into 1.5" x 9" strips. This made it really easy - there was not a lot of yardage to wrestle with. The blocks are paper-pieced. Some of the fabrics I used were really, REALLY ugly, but it's true what they say - if your fabric is too ugly to use in a quilt, you haven't cut it small enough yet!
