You’ll need the following ingredients:  2 tbsp carrier oil (jojoba, almond, or grape seed will do) 6 tbsp 100- to 190-proof alcohol 2.5 tbsp bottled (not tap) water 30 drops of essential oils (at least 1 of each: base, middle, and top) Coffee filter Funnel 2 clean glass containers  You’ll want to add roughly 30 drops in total. Start with your base notes, then add your middle notes, then add your top notes. The ideal ratio is 20% base, 50% middle, and 30% top. Pay attention to the scents that you are adding: if one scent is much stronger than the rest, you’ll want to add less of it so that it doesn’t overpower everything else. Use a high-quality alcohol with a high alcohol content. Vodka is a popular choice amongst DIY perfumers. Shut the lid and allow the perfume to cure for at least 48 hours. You can leave it for up to 6 weeks, which is when its scent will be at its strongest. Check the bottle regularly to see where the scent is at. Once you’re happy with the scent, add 2 tbsp bottled water to your perfume. Do this for 1 minute to ensure that the contents are well blended. Using a coffee filter and a funnel, pour your perfume into a clean, dark glass bottle. You can also transfer it to a fancy bottle if you’re giving it as a gift. You may want to label the bottle with the ingredients and a date on it so that you can keep track of how long it lasts. That way, you’ll know whether you should make more or less the next time around. To make a solid perfume (like a lip balm) instead of a spray/liquid perfume, try substituting the water with melted beeswax. You would add the melted beeswax to your perfume and then pour the warm mixture into a container to solidify. You can buy beeswax at most health food stores.

TL;DR in Vietnamese:
Thu thập nguyên liệu. Cho 2 thìa súp dầu nền vào lọ thủy tinh. Thêm tinh dầu. Thêm cồn. Để yên lọ nước hoa trong ít nhất là 48 giờ. Thêm 2 thìa súp nước đóng chai. Lắc mạnh chai. Chuyển nước hoa sang lọ chứa khác. Thử qua nhiều loại khác nhau.
