Rather then do all the sashing, I tend to go by quarters. I stitch the center sashing top to bottom. I then stitch the horizontal sashing in the center of the right side from the first center stitching line out. I then work on the top right hand quarter of the quilt. I stitch the sashing working from the center out and quilt inside the blocks. Once the top right hand corner is complete, I move to the right bottom quarter to quilt it.
Once the half is quilted, I turn the quilt around to do the next quarters. The second half I have to quilt upside down but doing it this way keeps less quilt jammed into the machine harp.
