I need a straw holder to try out with a client and do not have the patience to order one. Nor do I want to spend 20 dollars!!! I just cut the shape from two sides of a detergent bottle and punched holes. I can quickly make new ones when they get lost and adjust the size and location of the holes as needed. It stabilized the straw nicely when I drank out of this, so I think it will work with the client.
I use a heavy duty hole puncher from an office supply store and leather shears- from a sewing or office supply store.
