Laminating painted fabrics

I have been laminating the fabric painted and printed for my City and Guilds course. Most have been successful, the only one that really gave me trouble was the polyester, despite rolling for 30 min it still only attached in a few small areas. I'm not sure whether this will be seen as cheating or being innovative but after the third attempt I decided to try another tack; stitching to prefelt before felting.

This is what it looked like before felting:

And after:

These are the other printed and painted fabrics I laminated:
The organza was much more successful and I think the sheen on it is much prettier

Silk chiffon, this one resulted in the least puckering and the truest representation of the original design

Cotton muslin with carded top behind, this one has some lovely puckering that compliments the painted design:

Cotton scrim - I think the green merino has worked much better than the white as a backdrop for the monoprint.

This was the piece of cotton muslin with the glitter and 3D paints, the bronze 3D paint worked remarkably well but the glitter has lost some of its intensity during felting.
