We could weave text.

I found a 5×7 dot matrix font that might be used to weave text.

using Colors
using TabletWeaving

color(bit) = [ RGB(1, 1, 1), RGB(0, 0, 0) ][bit + 1]

color.(compose_line("HELLO!"))

We can also compose multiple lines:

using Base.Iterators

# 0 is the background value in the font used by compose_line:
PADVALUE = 0

MESSAGE = color.(
  safe_vcat(AlignCenters(), 0,
            insert_between(
                compose_line.(["THIS IS",
                               "A TEST"]),
                fill(PADVALUE, 2, 1))))

It would look better with a border:

MESSAGE =
    let
        # MESSAGE has already been colored so our padding
        # needs to be colored too:
        background = color(PADVALUE)
        padding = fill(background, 2, 2)
        safe_vcat(AlignHeads(), background,
                  padding,
                  safe_hcat(AlignHeads(), background,
                            padding, MESSAGE, padding),
                  padding)
    end

How might it look woven:

WOVEN =
    TabletWeavingPattern("Sample Text", MESSAGE;
                   	 threading_function = symetric_threading!)

output_file = joinpath(@__DIR__, "hello.html")
open(output_file, "w") do io
    write(io, string(pretty(WOVEN)))
end
output_file

"/home/runner/work/TabletWeaving.jl/TabletWeaving.jl/docs/build/examples/hello.html"

You can see the resulting HTML pattern file here.
