Except for bags, I also wanted to be able to sell some small things at my 'Open House'. I have the normal size bag organisers, but I did not make these myself. However, I will also put these down and I have ordered some foldable handbag hooks. These are small hooks that you can hook on a table and hang your bag from. These are especially handy when you are in a restaurant as we all know how dangerous it is to hang your bag from the back of your chair and how dirty it gets when you put it on the floor.
To get some small items I have sewn some small bag organisers for which I found this tutorial small bag organiser. Inside there are 6 ziploc sandwich bags. In these little bags you can put all the small bits and pieces that normally get lost in your bag even if you do use a normal size bag organiser. Things like plasters, toothpicks, cotton swabs, tablets, tampons, and lots of other small things. These small bag organisers will also be handy for a weekend away and may also contain some sewing threat and needles, special plasters to cover blisters for a weekend hiking or you can use them for shop vouchers, shop cards, etc.
