The most time-consuming part of making this boho style yarn wall hanging is cutting the yarn into 60 inch strands. You will need 15 bunches of 10 strands - making a total of 150, 60" long strands of this wool blend yarn. I needed to skeins of yarn to cut this much, but didn't use up both skeins completely.
Honestly, you can use any yarn you have on hand in any color. I chose this wool blended yarn though because it was neutral and natural looking, and I hung it on a green wall. If you were going to hang it on a tan or gray wall, you may want to add a splash of accent color into your yarn bunches.
