Differential Shrinkage...Will it Work?

Photo 1- Cones of the four yarns I'm using in this project. Black and red Supersheen Acrylic, and black and red 2/28 wool.

Photos 2 and 3 - These show the warping process.

Photos 4 - 9  Half the first sample worked! The bottom half with the acrylic weft was disappointing, but the top half with the wool weft worked well. The black "felting" yarn shrank the best (as you'd expect!), the red merino was OK where it crossed the black wool, but areas of weave with a red merino warp and weft were reluctant to shrink so much.

I've just uploaded some more photos of samples from this warp. I've tried to include a before felting pic, and then the felted version.
