Smaller the number the the smaller the chenille. Personally I don't use anything smaller then #2 and can tie from 1/48 or even smaller all the way to 1/4 Oz, but do have to double wrap 1/8 and 1/4. However I mostly have started using #3 and for sure if it's what they call New Age because anytime you add Crystal in Chenille it's less dense. Now if I use Crystal it's going to be #10 or #12 as that is what I like and it lays back some when wet so t's not as big as it looks when all spiked looking.

Here is the size chart....
