Closing off stairs, how?

[Surgubbe]

A huge amount of dust is coming down from upstairs. But now we want to hang clothes under the stairs so we want to close the risers(?). Either make them completely sealed or leave a 5 cm air gap at the top of each step. As long as the dust doesn't have a clear path.

What should I use? Preferably nail them in with brads and then use a quarter-round behind so they can't be accidentally kicked away.

Any tips?

There are enormous amounts of dust coming down from upstairs. But now we want to hang clothes under the stairs so we want to close in the risers(?). Either make it completely sealed or leave a 5 cm air gap at the top of each step. Just so the dust doesn't have a free path.

What should I use? I prefer to fasten it with brads and then quarter round behind so they can't be accidentally kicked off.

Yes, there are pre-made options to buy, alternatively, you can buy mdf or laminated board, cut to size, and paint.

It's easier to put full boards under the stairs, so it becomes completely tight.
