Fishing Line (or any type of string you want)
Small binder clips/ butterfly clips (Clothes pins would work as well)
Picture(s) you want to hang up
Step 1: Step One: the Picture
Cut the paper where the clip ends, so you get what you see in Pic 2
Make sure the cardstock is long enough to fit on the back of your picture.
Put the binder clips and card stock on the back of your picture, and tape it close to the middle. (Pic 3)
You should now be able to hold the picture by just holding the clip.
Step 2: Step 2: the Wall
Find a wall where you want to put your pictures. (Pic 1)
Figure out where you want your first (or only) string, mark it with a pencil. (Pic 2)
Take one of the eye hooks and screw it into the wall at the mark. (Pic 3)
It is okay if it doesn't go through all of the drywall, mine didn't and it can hold over six pictures.
Measure the height of your eye hook if you haven't already. (Pic 4)
Measure to that height on the other side of the wall and mark that point (Pic 5)
Screw in the other eye hook.
Tie some fishing line to one of the eye hooks. (Pic 6)
Roll out the fishing line until you get to the other eye hook, then roll out some extra. Tie the end to the other eye hook, tightly.
You will have excess line, so cut it off. (Pic 7,8,9)
You now have completed the holder for the pictures. (Pic 10,11)
Step 3: Step 3: Finishing
Add your other pictures to the line. (Pic 3)
And add more lines if you want. (Pic 4)
