Fused plastic portrait 2

I am wondering about creating a Victorian photo album of fused plastic portraits? How would that work? Or are these icons? Should the people be real or imagined - they have been invented so far...   What other materials would I need?  Would it be interesting?

I have a new sewing machine and I'm not sure what I was doing wrong yesterday but the stitches were not right.  Today it worked dreamily. I even used the knee lift! I will have to go back and prick out the other stitches and correct...
