Even though these days we do not have as many plastic bags as we used to, we still have some. They are useful for lining bins and I like to separate meat, bleach and dairy products from my other shopping. I don't want lingering smells in my cloth bags.
The tea and coffee cosies are lined with wadding and some white fabric. They keep the pots lovely and warm and ready for a second cup.
The bag of bags hangs on the back of the kitchen door and we just stuff plastic bags in whenever we have them. It is simply a long tube, hemmed at the top and with a handle. It has a casing at the bottom edge and elastic threaded through it. This keeps the bags in place and and allows easy access to them.
The top of the bag has a handle for hanging.
You just stuff bags in the top and pull them out at the bottom.
The bottom of the bag is elasticated.
