I suppose you could say there's a few types of glamour spells. I feel it's best to start with your own definition of glamour. What do you want to achieve or do? Weight loss? A different appearance? I feel these are possible through spell work. For example, you could do a glamour to make yourself look different through others eyes. Or, you could do a weight loss spell and work with the spell to achieve your goal. And I certainly agree that you should write your own. That's usually better too because it has your own emotion and tends to be more powerful. Hope this helps!
