【ファスナー付き保冷バッグの作り方】返し口なしで作れる！

*What to prepare 2 pieces of front cloth: 37 cm (W) x 20 cm (H) 1 piece of bottom cloth: 37 cm (W) x 22 cm (H) 4 pieces of zipper cloth front and back: 37 cm (W) x 7 cm (H) 2 pieces of handle: 34 cm (W) x 10 cm (H) Cold storage sheet (aluminum sheet): 37 cm (W) x 58 cm (H) We made a cool bag with a zipper. It is perfect for rehydration and lunch bags as the weather is going to get hotter. It is large enough to hold three PET bottles. The bag itself and the cooling sheet are made in the same way, and all you have to do is to attach the zipper. It is easy to make because there is no opening to turn the bag over and there is no process to turn it over.
