Just a little numerically challenged.
But I finally took a deep breath and did the math: my three skeins of Handmaiden Sea Silk won't be enough to complete the leaf and trellis rectangle on p. 54, because I am a Loose Knitter. Based on my progress to date, the center panel will require about 2.25 skeins, and the border will need roughly 1.75.
So I ordered another two skeins online. I'll use them for the border, in hopes that any lot differences in this hand-dyed yarn won't matter much.
Wow, I feel so much better. ;-}
