scent blending with essential oils

Today everyone was back at work after the Thanksgiving holiday so I had them all smell the scent blends I had created last week. I have pretty much zeroed in on wanting to create two new scent blends – Lemon Zest and Lavender Mint. Last week I had created a number of blends that I and my staff smelled and rated. Today I had them smell the blends again and see how they had “aged” in a week.
