PLEASE don't say that you're not pretty.
Let me tell you a story: a long time ago, I met this really really UGLY Doctor. I could barely look at him. That's how esthetically ugly he was! LOL. UNTIL.....
Until he opened his mouth. He was charming, kind, funny, witty, intelligent, and humble. When I left the hospital, I thought he was the SEXIEST man that ever walked the face of the planet.
That was 17 years ago. To this day, I have NEVER forgotten him. N E V E R !!!! If he wasn't married, I would have cast every single love spell on him that I could imagine.
Outer appearances, in my opinion, don't show what's in one's soul.
And you sound like a kind and warm person. So, PLEASE don't say these things about yourself.
Here's an array of spells that you will find has many attraction spells in its content: http://www.luckymojo.com/lovespells.html
Look at these oils: There's attraction, bewitching, come to me, etc that you can use on yourself http://www.luckymojo.com/mojocatoils.html
You can also use the sachet powders, the candles, incense.
There are also spell kits that you can use. And the list goes on for enchanting yourself.
As far as the candles, I don't know what size candles you have. So, can't answer that.
AS far as how many oils to use on the candle, I think that this is a good start until you know exactly what you want. Odd numbers are traditional in Hoodoo, 7 is good for luck, 9 is good for success.
