Check out these fun ornaments!! Easy to do on a budget too. I love these dried chilies, orange slices, whole oranges, whole limes, cinnamon sticks, and pinecone ornaments
this post to see how to dry orange and apple slices. I would image you use the same technique to do the whole orange and lime. Just cut slits around the oranges and limes and squeeze out as much juice as possible without disfiguring them first.
