I'm wondering too? *4u

not sure on this one, someone is bound to anwer your question. All I know it is a type of embroidery Jo

Trapunto
Trapunto is a whole cloth quilting technique which produces a raised surface on the quilt. Trapunto patterns consist of vines, leaves, grapes, cherries and so on. The vines and straight line patterns are threaded with a soft yarn or cording. The rounder shapes are stuffed with small amounts of batting inserted from a small slit made in the backing fabric. After the shapes are stuffed, the slit is whipped stitched closed. A second backing fabric is then added to the quilt and normal quilting is done all around the previously stuffed shapes.
Another style of Trapunto uses a loosely woven fabric for the quilt backing. Then, instead of making slits in the backing to stuff shapes, a needle is used to carefully push the backing thread apart to form an opening for the stuffing. The threads are then carefully pushed back into place. This eliminates the need for a second backing fabric.
Trapunto originated in Itay in the early 16th century. It appeared in the United States in the the late 1700's and remained popular until the Civil War.


does that help

This is a decent video of the process.;)

You already have an excellent video answer. I just thought I would add what dear Merriam-Webster has to say about it.

Etymology: Italian, from past participle of trapungere to embroider, from tra- across (from Latin trans-) + pungere to prick, from Latin — more at trans-, pungent
Date: circa 1924
: a decorative quilted design in high relief worked through at least two layers of cloth by outlining the design in running stitch and padding it from the underside
