(Optional) For the background, I use watercolor. Please look at the pictures I have here on Fiverr for an idea on what it looks like. :)
I will write the text you want, scan it in hi-res and send it to you.
I use markers, brush pens, and regular pens. :)
Absolutely! Although I prefer to use white ink when writing on a colored background as it looks better in my opinion. But if you don't want it white, it won't be a problem. For the background, I use watercolor.
Yes, I can do it. That won't be a problem. :D
