This idea sprang out when I make a small knitting project and need a small pin for hold my thread. I want something lightly. All of my pin are big and they're too heavy for my project.
So again and again paper clip has a way out for me :D
Look at my picture instruction from step 1 till 5 and see the finish pin. Easy to make, simple.. and usefull too.
Hope it could help you too.. Happy knitting !
