Tiff...you sure must have one heck of a nice scrap bag! Your blocks look wonderful, but then I knew they would. I don't see anything that needs to be redone :D
You probably don't need to "resize" your tris"...if you are using the 4.5" blocks..just click on"size from quilt" under options and it will set the tris at 5 x 8 which is the correct size if you are doing 4.5" blocks with sashing.
