One of the things we'll be needing when the Consort goes back to recording is a set of pop filters for the vocal mics, as the condensers are far more sensitive than the dynamic microphones we'd been using. Unfortunately, the cheapest ones I could find locally were about $20 each.
However, using microphone clips, small wooden embroidery hoops, some stiff pieces of wire (I had some bicycle spokes handy) and some stretchy fabric, I put together a set of fairly decent filters for under $6 each. They're not pretty, but Peter Piper can pick his peck of pickled peppers properly protected from pesky plosives.
