What can I say, it's ghetto. I made it myself late last night using only a wire hanger, a pair of pantyhose, a pair of pliers/wire cutters, and an embroidery hoop. This particular model is especially handy if you are using a mic stand with a boom because it allows you to change the position of the boom and stand without having to mess around with the pop screen itself.

Step 1: Assemble Your Supplies.

Get the following:
A pair of trusty pliers with a wire cutter.
A pair of panty hose.
A wire hanger.
A 6" embroidery hoop.

Step 2: Straighten Out the Hanger.

Pretty simple.

Step 3: Cut Wire.

Cut wire into 3 equal pieces. They should be 9-12" each, depending on the length of the wire and the size of your microphone head.

Step 4: Bend the 3 Wires.

Bend the 3 wires into L shapes, with the bottom part about 2" long.

Step 5: Make a Circle

Take a leftover part of wire (the rounded top works well for this) and bend it into a circle and twist the ends together. Make sure that it fits a little bit loosely around the microphone, just under the head.

Step 6: Try It on for Size.

Put it on the mic and make sure it fits a little bit loosely, just under the head.

Step 7: Attach the L's.

Bend the L's around the circle.

Step 8: Try It on Again.

Fit the whole contraption on the mic.

Step 9: Make the Screen.

Cut off a leg of the panty hose. Take the inner ring of the embroidery hoop, put it in the leg, and shove it all the way down to the toe. Make sure the panty hose are kind of tight over the hoop. Knot it and cut off the excess material.

Step 10: Prepare the Outer Ring

Take the wire contraption and arrange it as shown in the picture. Take the outer ring and center it over the contraption and note where the ring hits the wires.

Step 11: Bend the Wires

Now bend the wires at the spots where the ring hit. Bend them upwards at a 90 degree angle.

Step 12: Put It All Together.

Now loosen the outer hoop as much as it will go. Hold the 3 bent wires on the inside of the outer hoop and insert the inner hoop. This will be quite tricky and unless you have 3 hands, you might need a friend to help. Or hold them all in one hand while you fiddle with the inner circle. Once you have the inner circle in place, tighten the outer circle a little bit. Then arrange the wires so you have them at 10, 2, and 6 o'clock. Tighten the outer hoop as tight as it will go. Then insert your mic into the circle. CAREFULLY adjust the screen so you have about 1-2" between the mic and the screen itself. Then you're done!
