I need to get a roman 'sticker' made to travel from Thailand into Malaysia. Although the shops here in Hat Yai seem fine to make those horrid black stickers for cars, I was thinking about getting some information about the minimum character size for bikes. When I see some bikes come through Hat Yai, i can see some have tiny letters, probably illegal, but also well worth a go. I don't want a huge sticker thats suitable for a car across the front of my bike. Also any info about the legal size of characters would be good, i looked elsewhere and couldn't find.
