DIY tiny moss pole????

Recently I got really into propagation and as a result I have a lot of baby plants that are now living in both soil and semihydro setups. They are still small but have a few leaves each and are starting to get aerial roots so could probably use some support.

I wanted to experiment with putting some of them on a moss pole, but moss poles only come in huge sizes. What can I use to DIY a small moss pole? Preferably something I already have lying around in my house.
