Here are the calculations:
2.5 yard warp
And my biggest worry was not having enough yarn! I used less than half when I warped it, so I think there will be plenty! Maybe even some for my friend to knit a matching hat with in the end! This is going to be so pretty.
Also, I found out the yarn was from DebbieB at this website! This is turning into a huge combined effort of ravelers from ravelry.com! The recipient in from ravelry, and so is the yarn maker and the weaver! That's pretty cool!
Here is the pattern:
It's the same pattern I used in the perle cotton scarves for my sister and her friend in December and January, but these will be wool!
