Last year some time I read about a fabulous pleating tool made by Angie Knowles called the Quick Pleater.
Several of you have asked what it is I used to quickly and easily make the pleats on my ottoman slipcover
You can purchase yours from Angie, or you can make them yourself (or have someone else do it, as I have). Mine are a little crude, but do the job well.
I used the 4” one to make the pleats on my ottoman
While at Wally World the other day I came across this tool to make pom poms for $1.97
