This project has been nesting in my mind for quite a long time and finally yesterday I did it.
Thing always look harder than they are actually.It took me less than an hour to do it stitching by hand.I didn't even need to take my sewing machine out.
So, the dress was size 6, already
small but as the waist line was high the skirt part was long enough to be worn separately.I cut the top off leaving a couple inches for sewing.
I measured the elastic and hand stitched it together. Then I put it around the waist line wrapped the extra fabric from the top around it and hand stitched it.It turned out perfect and she loved it swirling and twirling in her new/old skirt.
