Thought i would show how i have made my hand plates.
Started off by making a template .
The measurements were used to make my template out of thin card . I used the back of my hand and cut out and refined a paper template until i was happy with size and that is how i arrived at the measurements above.
Once i had my template i rolled out some plastercene until i reached a thickness i was happy with and then cut out my two base shapes.
After the base was done i re rolled the plastercene
