The thing about using invisible thread is that you can’t see it! But after you wash it you can easily see where it needs to be “fixed”; as it ravels a bit. I have the damp quilt on my table to finish drying.
You can square a damp quilt by tugging a bit here and there, then allow to finish drying flat. I then looked for places that I missed stitching, and marked by laying a pen, stiletto, glue stick, etc on the spot. When the quilt is dry I will mark with a straight pin. Then turn under the edges & take to the machine to stitch down. The binding I made extra wide to make it look like a wood frame around the Rose window. The quilt hanging sleeve is on.
It is soon ready for a label! I am rejoicing.
