How ideas on how to do this?
Thanks!

I'd do vertical piping in white (maybe a round #4 or #5 tip?) and the horizontal basketweave in the red/orange brick colour.

That way, the white piping might almost look like the grout between the bricks.

Do you know about these? There is a brick one.

Thanks!

That's what I was thinking using the thinner tip in white. Thanks for giving me a number tip to use.

Yes, I've seen the brick imprints but can't seem to find around here and won't have time to order. Those look very easy.
