OH! Forgive me...I'm foggy today. The only experience I have doing this was when a customer asked for a sandlewood/jasmine combination. I used those cotton pads you get in the cosmetic aisle of stores. I put different ratios on each pad and put them in individual snack-sized Baggies. I used little droppers, the kind that fit the really small brown glass bottles. I don't know if that's what you're looking for, but it worked in that case. But...what about those paper "sticks" they use at perfume counters? They seem to hold scent really well. Don't have a clue where you'd get them, but you could ask someone at a perfume counter. They'd look a heck-of-a-lot more professional than cotton in a Baggie!
