What you can do with a size 6 depends on your size, your baby's size, your wrapping skill, and your wrap. Thicker wraps tend to wrap shorter than thin wraps and in general the longer you've been wrapping, the more you'll be able to do because you'll wrap tighter and higher. The carries below are our best guess at what most people can do with a size 6. If you're very petite, you'll probably be able to do all of these and the size 7 carries. If you're fluffier or broad shouldered or chested, you might find you want a size 7 for some of these carries. For a really good idea of what you might be able to do check out this thread from thebabywearer where people have posted zillions of pics of carries they can do with a size 6.
