Yes, custom orders are trending now, but finding someone who will do it for a reason is a real quest. I'm looking for it myself.

You're right, custom tarps are always better than universal ones. I got mine from the brand tarpstiedowns. They have both canvas and vinyl options - always made to measure, high quality, and durable. If you have a specific task, feel free to write to them, they will advise you on the best material and make it according to your design.
