An interesting array of micro bubbles have peppered the interior.  I am unsure if this adds or detracts from the composition.  It is the first resin pour I have done in a while (the last one I did was for a student project some time ago).

Now I am constantly thinking 'hmm, I wonder if I could encapsulate that?' as I hold small specimens of twig or petal aloft.

What would you preserve in resin?
