Thank you for viewing my work (*^^*) I've made a furoshiki-style pot cozy that's great for keeping things hot or cold. It can also be used for cooling, so I wrap dishes that don't fit in the refrigerator during the hot season, add a large ice pack, and use it to prevent food poisoning. Two layers of aluminum sheet are inserted between the fabrics, which helps to keep the temperature down. Please note that there are patches to avoid wasting the large fabric. I hope this will help you save a little money as electricity bills rise. *How to use for residual heat cooking* After boiling completely and seasoning, wrap the lidded pot and secure it with a clip to seal. This prevents the food from breaking down, allows the flavors to soak in, and makes it delicious. It's great for things like oden and curry, which simmer slowly. Recommended points of the furoshiki type! *Easy to wash by hand, and hygienic. (Cotton types are difficult to wash and dry because the cotton tends to bunch up. You might also worry about dust mites when you use it.) *Compact. It folds up into an A4-sized envelope when folded eight times. You can stand it up in a gap like a book, so you don't have to worry about where to put it. You won't feel the hassle of taking it out and putting it away, so it's easy to use for everyday simmered dishes. *Compatible with various pots You can wrap various shapes and sizes, such as earthenware pots, frying pans, and double-handled pots. *Easy to maintain temperature. I've researched and recorded the temperature changes, depending on the room temperature and the amount of food being cooked. *Energy saving You can turn off the heat quickly and save energy. It's also useful in times of disaster. *Prevents forgetting to turn off the heat If you're forgetful or in a hurry, you might worry about whether you turned off the heat. It's a reassuring factor because you can be sure it's safe once it's wrapped. *Keeps food cold and hot Don't leave food out in the hot season! When it doesn't fit in the refrigerator, I put in an ice pack and wrap it. For keeping rice cooked in an earthenware pot or oden warm. *Instagrammable You can take pictures of delicious, non-mushy dishes. The front is checkered, and the back is black. The sheet is sewn in. The size is about 65 x 65 cm. It can wrap an eight-gou earthenware pot or five boxes of tissues. Precautions for use Do not leave it out for a long time at temperatures (30°C to 40°C) where bacteria can easily multiply. When using it for cooling, please check the melting condition of the ice pack. Please note that the sheet is difficult to sew, and there may be some tension. Thank you.
