Tie-dye, muslin, polymer clay

Yes! I think I have got it, at last!  The tie-dyed fabric is bright, colourful, garish....the muslin is dull and a bit boring. The clay pieces disappear on the fabric. But.....what if I cut a window in the muslin, revealing a flash of colour; do some stitching on the fabric to create texture, and use the above as a frame for the polymer clay piece? I think it might work, and I will be using most of my materials, as planned.
I can play on the squiggly lines created by the elastics, in the tie-dye process.
The polymer clay blanks could either be made into brooches ( by adding a pin back), or a pendant (by adding a clay strip, and making a tunnel for a cord, on the back)  That way, I can remove them later if necessary, and also won't be detracting from the pattern, by making button holes.
