There are three different sizes since I don't think the bamboo skewers would be a consistent size. I am using 10-inch bamboo skewers. I think the slightly longer skewers are thicker, so there are two other files with a wider hole for the skewers.
If needed, use glue to hold the skewers in place.
I used two small screws to hold it onto the wall since it doesn't need to support a lot of weight.
Ignore the holes I need to patch, I was replacing an other hook system.
