Attaching Rows

Yesterday I assembled all the sashing rows for Wild and Goosey. Today at "Quilters of the Big Room", I got about half of the rows stitched together:

You can see I haven't removed the papers from the sashing units yet. They are helping with the stitching; no seam allowances get caught up in the seam allowance when the paper is underneath, and when it is on top I stitch along the line and know the seam allowance is accurate. However it won't be a fun job to remove all the paper later.
