I love reusable cold packs—they’re soft and squishy, and enclosed in durable plastic to prevent leaks and drips. But the covers they come with are too thin to really insulate my skin from the direct chill of a frozen pack. Hand-knit washcloths worked much better, but the coverage wasn’t quite right, and cold packs tend to escape. The solution was clear – my cold packs needed their own little envelopes.
