Well the heads on our machines can do like 5 or 6 colors without having to change threads out, so it won't be a problem. I do this all the time and I think these will look fine in a 3.5" wide size.
Sorry guys, work was kinda insane today, so I spaced the pricing. I have classes tomorrow, but I will get it on Friday. I will then post the price and if everyone is okay with it, I will order them. Once they are done, I will post a pic, then start taking orders.
