Here's how I arrived at my estimate
- I based my calculation on a hammock project in "Macrame- The Craft of Knotting" by Jacquline Short.
- The finished length of the hammock is 6 feet. She has used 25 yards per length.
- 1 yard = 3 feet. Therefore, the length of each cord is 25 * 3 = 75 feet. (Each cord is folded in half for the lark's knot).
My Doubts about this
Even folded in half for making the lark's knot on the handle, I'll still have 12 feet per length of cord. That's twice the height of a man. For a 2 feet bag? I don't know. What if a lot of yarn goes waste. They'll be too short for use in any other project.
I also remember reading somewhere a long time ago that the length of yarn should be 8 times the length of the project. That is simply
2 * 8 = 16 feet = 192 ".
Since this is an experiment and I don't mind having a shorter bag, I decided to go with this. Each length I cut was 16 feet.
When I finish this bag, I'll have some credible answers.
