This is a one-piece bowl and mat centerpiece. I experimented with wet-felting an inclusion into a flat square layout of alpaca wool roving. I wrapped a plastic egg in dark gray roving and then placed it on my layout of cream roving, then covered everything with a few more layers of cream. After the felting process was complete, I carefully cut a hole and extracted the plastic egg. The result is a bowl with a dark interior that is integrated into a cream mat. Three edges are trimmed and the fourth is left raw like the top of the bowl. I absolutely love this piece. Yes, I will be making more.
