Hm I dont know how busy you are. But there is a website I sometimes print posters with. Called posterxxl. you could upload the pic for example in the size 80x60 cm and I give you my Bank data oder you send it as cash on delivery etc. But this homepage is only in german.Thats a problem. And this will be the price for printing only not for your efforts. What du you think any suggestions?
I found posterjack. com. this page is available for great britain as well. I think the 100 on 70 cm option at posterjack would be the best. Since your work consists of paths there should not be any problems by enlarging ? thanks in advance
