I think I am probably in the perfect nexus of data-lovers, covid-cautious people, and crafters to ask this:

Has anyone out there made a #knit or #crochet cozy for a CO2 monitor (I just got an #aranet4) that helps cushion it from bumps but also keeps it functional with good airflow? Thanks!

@sundogplanets Yes! I #knit this from scrap wool yarn, then felted it in the washer and sewed the sides. The elastic and button closure allows surprisingly good air flow; I usually put the #aranet4 in so that the vents are towards the top.
@JosetAEtzel Oh THANK YOU for sharing this! I"m going to start one one right now!
