Hi Lucy, the full details are in my latest blog post here on UKQU under the Mystery Quilt section.
It’s piecing with a lot of applique (and/or embroidery if you want) its approx. finished size including border is 48″x48″, it’s 40″x40″ without a border, but could always be made larger if you wanted to add to it.
Hope this helps, but please do ring me if you would want 07940133116
