These directions seem o.k. if you don't use too thick of a batting. With this method, you are not turning the whole quilt inside out. Your just working with the outside edges.
Quilt your layers together, but leave the outer 1" edge of your quilt free from any quilting.
- Trim all layers even with quilt top.
- Fold only your quilt top right-sides together towards the center of quilt and pin.
- With right sides together, sew ruffle on top of quilt back and batting.
- Iron ruffle up away from backing and press seam allowance down towards inside of quilt.
- Remove pins from your quilt top and unfold. Now fold the quilt top under 1/4" all the way around to hide raw edge. Press.
- Top stitch all around the quilt sewing through all layers. You could use a decorative stitch here to add more detail.
Hope this helps. Good luck!
