man ur hats are crazy when your changin colors are you just keepin the color your going to use on the inside of all ur stiches then reverse em when you wanna change the color?? like on your black grey white and blue diamond hat did you just use black grey and white switch all the strings in and out when it was time then sew the blue on when it was finished?? hope that kinda made sense it gets confusing when asking a question like that haha
