Don't panic, the
acrylic medium isn't anything special. What you see in the photo is
a jar of Golden (the brand, not the color) Soft Gel Matte. Some craft
stores carry this stuff in the section with acrylic paints. Some don't.
If you can't find it, you know what else is an acrylic medium? MOD
PODGE! Mod Podge is everywhere.
Jewelry wire comes
in lots of colors, and if you can find some to match your wig, get
that. I didn't have dark brown wire so I used gold, and there's almost
no show-through.
Step
1: Measure Once, Cut Twice
:
Clip
some hair from where it won't be missed on your wig. Alternately,
trim some extension hair to the length you need. Lay it out flat on
your wax paper, and cut a length of wire the same length as your hair
plus a couple of inches to make a loop at the end. Set the wire aside
for now.
The
final width of your strand will be half the width of the hair you
lay out, so clip accordingly.
Step
2: Goop

Time
to paint your hair with your acrylic medium. Start in the middle and
brush toward the ends. Give it a good coat and make sure the medium
goes all the way through. Don't worry about the edges or stray hairs
or unevenness at the tips or any of that--you'll be trimming it later.
Step
3: Yup, It Sticks Up

When
the medium is dry, use the table knife to gently peel it from the
wax paper. You will note that at this point it's pretty damn sticky-up.
But it lacks discipline!
Step
4: Installing Some Wiring

Set
your strand down, and coat the side facing you with another good coat
of medium. This is to glue it to itself and the wire. Set the wire
in the middle of the strand, and fold the strand gently in half over
it. Ideally, the hair will extend just a little bit past the end of
the wire. Fold the wax paper over it and lay a book or something flat
and heavy on top of that to keep your strand flat while it dries.
(This
is where I have to admit that I go off-label. Instead of using more
medium to stick the wire to the hair, I usually use fabric glue. It
dries more quickly and holds well, but I don't recommend using it
unless you're confident in your ability to keep it smooth. Disturbing
the medium while it's drying won't do much, but messing with fabric
glue can leave icky white gunk on your strand.)
Step
5: Sticks Up With Discipline!

Yup,
it sure does stick up all right. But now you can bend it! Bend it
slowly and gently and be amazed by the nifty zags and curls you can
manage. At this point you can trim it to remove loose hair and uneven
edges and put a tidy point on it.
Step
6: Attachment

Poke
the end of the loop on the end of your wire through the wig and stitch
it down. Blanket stitch works very well. I used white thread for visibility
purposes but you'll want something that matches your wig fiber. Be
careful not to stitch your wig hair down by accident.
Step
7: Success!

A
very specific portion of your wig is now officially immune to gravity.
Wear it with pride!
