This ible talks a lot about a triple single. You can find out how to make this on my instructable rainbow loom- three way bracelet (triple single)
Step 1: Materials
Rainbow loom, hook, and black and white bands.
Step 2: Starting
Take one band and put it forward from the middle. Then put one band out to the right, then the left. Take two bands and put them both forward together on all three lines 5 times, on the outside 2, put 2 black bands on the second one.
Step 3: Add Half Diamonds
Add half diamonds all the way shown in the pic just like a triple single. Turn your loom around so the arrow is facing you.
Step 4: Hooking
Hook the outside two just like a triple single. Take the band that was part of the diamond and take it off the hook so when you hook the middle one it will go over the diamond tucking it in. Hook the rest.
Step 5: Finishing
Hook the rest to wear they come from. On the last one you hook, once it's hooked, from the put side pull the bottom part over the top. Pull off the ghost.
Step 6: Done!
Your ghost is done. Enjoy! Comment, favorite, follow!
