I have made some barriers on my new track and looking at options for adding advertising to them. I've seen some for sale on ebay but the sizes don't quite fit what I need. I've been trying to find a basic online print shop for printing a design onto an a4 page on sticker paper (which I could cut out), but everywhere seems to just want to offer more rigid formats and certain shapes.
Does have anyone have any suggestions for online printers? Or even a more suitable solution/suggestion than just getting them printed on one big sheet if the option exists somewhere I haven't found.
