It's a very simple love spell. (I wrote an article on the candle craft of Wicca and witch spell casters and in it there is some info on how to anoint and prepare candles for spells.) Take the candle you're using to represent you and carve your initial into it. Then do the same for the other person involved with the other candle. It needn't be big lettering or deeply carved, it's more there as a symbol and the process of carving it in is building energies within you.
All you need do now is heat the wax at the bottom of the candles and then press them together, so they're side by side and sealed - and light them! You can prepare some wording for this, a declaration of your feelings, but I do not always do this. I am content with the power of the light, heat and wax melting together and becoming one.
Most candles today do not leave any wax behind of course but if yours do, keep it for a few days to prolong the energies around you.
As ever, I feel obliged to point out that love spells are not about bending the free will of others. Love is a special feeling, one to be cherished. So always work with its beauty rather than trying to force your feelings onto another.
