There is a battle between pins and scissors in the world of sewing when it comes to which one is more essential and is used more often. At the end of the day, both of them are extremely important and you probably wouldn't be able to complete any project without both of them. It can be frustrating sometimes when you are in the middle of a project and suddenly lose your scissors.
A simple solution to help with this is to tie the scissors to the sewing table or the machine itself with a long string so that you can still use them and don't have to worry about losing them.
