I am aware of the fact that there already are thousands of dream catcher tutorials on Cut Out + Keep so I'm only going to explain how you can add beads.
I'm using my dream catcher as a necklace. In a few days I'll be flying to Spain for a holiday. I really enjoy flying so I added an aeroplane to combine two of my biggest loves: planes and sleeping.
NOTE: For the tutorial I used big beads so it's easy for you to see what I'm doing. I'd recommend using small beads and a needle. I used crimp beads because they are nice, shiny and have big holes.
