DMC Light Effects

I bought some of this in a pewter color thinking it would be great to use if I ever get around to stitching that Frank Lloyd Wright window. Yesterday I tried it on a small spot in a sampler. Um. Can't imagine using this to backstitch a piece that's 300 stitches long...This stuff is stiff and not at all easy to work with. Started by trying to use two pieces, ended up using only one. I wonder if Thread Heaven would make it any easier? Guess that'll be the next expirement.
