Creating Sigils- Best Method? Options

Hello everyone! I wanted to hear everyone's thoughts on what they consider is the best method for creating sigils (i.e. words, pictures, or mantras)? Obviously, everyone has different results based on their experiences, so please share which method worked best for you, or if you think a combination of words, pictures and mantras are more effective. I'm in the starting process of creating sigils, and I plan to try different methods, both by the book and creating what works best for me, so I will report my finds as I see results. So far, I've only experimented with the word method, mainly because it was the easiest, and I want to be come proficient at one way before I attempt another. I also incorporated a symbol within the symbol I created out of words. I.e. If I'm making a sigil for love, I drew a symbol for what I feel love means to me. Although I'm not sure if this was a good idea, because I had created various sigils, put them aside until I forgot which each one represented to charge them at a later time. But having incorporated a symbol within a symbol for the intent almost gives it away. (IMG:style_emoticons/default/black eye.gif)

Also, feel free to share different methods for charging sigil!

Everyone here has given some sound advice and highly recommend that you follow them. Why I suggest is to try and make them from scratch if all possible. This way your putting your energy into the sigil. If you do buy or get a sigil from another maker. For example buying a amulet or picture of a Ankh, be sure to take the time and meditate with it and charge it with your energy before using it.
