Apologies for the yellow tone of this photo, it seems to happen when I take photos indoors at night without flash. What I want you to see is the difference between the trapunto on the left (Done the normal way with water soluble thread and then the excess cut away) and the two layered batting on the right. There is almost no difference!!
This quilt is just under 80" square if it were any bigger I would have to go back to the cutting away method as it just wouldn't fit under the harp of my machines but next time for a quilt this size or smaller, this works for me. Also be warned, I don't think with a cotton batt or a heavier weight poly, I still would have found it impossible to fit under. So the Quilter's Dream Request Poly and the Hobbs wool combination works for me.
