yes i guess i could, but i think the alternating sizes make the dragon look more realistic. hahah i'm paranoid myself and my secret ingredient is clear nail polish. i'll do the regular knot, coat it with clear nail polish (just let it air dry. don't blow it bc some polishes will turn a milky white color if you do.), and use the metal knot hider thing. OR you could use the little metal crimp ring, flatten it, and then use the knot hider. If you don't know what i'm talking about, i'd be glad to take pictures and show you.
I dont know what the "metal knot hider thing" is hehehe
