I used to teach embroidery at home parties (28 yrs ago!!)for a co. called Creative Circle Stitchery. I used to do a stitch that filled in an area and then you trimmed off the top to allow it to stand up kinda like rug fibers.
But I can't remember the name of the stitch and when I tried to recreate it now I wasn't doing something right.
This is used to fill in the body of for example a teddy bear or a bee or something like that.
Maybe someone knows what I am talking about because I remember making these but it has been so long I can't remember how to do it any more
Sorry I'm not much help. I thought a satin stitch would work but it isn't quite right.
