I found a further great free download resource. Mike at Scenerybuilder.com has this great high quality FREE brick terrace to download and print.
Mike has also produced two types of brick design on paper to download - just choose the scale you want (4mm for 1/76). I'm really impressed by Mike's efforts. The finish is very professional and I would encourage you to donate a couple of quid via Paypal to say "Thank you" for his efforts and encourage future production.
