As Promised here is a video of how I a doing the trapunto on the whole cloth quilt. I am using Bulky 5 (at least that is what the packaging says ) Roving Yarn and a very large needle. They sell Trapunto needles but they basically are just really big needles so I am using one I bought in the Upholstery section of the store…they use them for tufting buttons.
I think you can see in the video what I am doing. The needle goes in from the back and you want it to be between the backing fabric and the batting (this makes the front side smoother) I go in one side of the area to be stuffed and out the other, cut off the yarn…and then pull the tails in , sometimes it is harder than others but the needle works to get the tails inside the layers. as I add more yarn I try to align the yarns and push them into place with my thumb. Keep going until the area is filled. there will be some visible little holes in the backing fabric…these will close up once the quilt is washed.
Here is the video.
