I picked up this wool from Michaels and I found the birch log on one of our family hikes.
Yep, did I mention I'm a hiker now? that's a whole other story lol.
First start by cutting 8 strips of wool (each about 5-6 ft long).
Place your stick/log between two chairs or other surface.
Grab one strip of wool and fold it in half to make a loop,
put it behind the stick/log and pull the ends through the loop.
Continue this with each strip of wool, placing them approx 1-2 inches apart.
You should end with something similar to the image below - 16 strips hanging.
Grab the first four strips of wool and proceed to make a Macrame square knot.
Continue across until all strips have been used.
Continue to the next row leaving two strips out at the start to create the pattern.
Once complete cut the ends even (or leave them uneven if you'd like - anything goes).
I ended up hanging this wall art in my sons baby room and I really like it.
