Kim, of Chronic Ennui, crocheted a lovely cream-colored wool version of this scarf, so I was compelled upon seeing hers to go forward with my plans to crochet a 100% cotton Anne for myself. I'm so glad I did - I love this one even more than my first Anne and can wear this comfortably all summer.
Initially, I started mine with a 5.00 mm hook. I wasn't getting the result I wanted -- which was a really dense and stiff motif -- so I switched to a 4.00 mm hook. Although it turned out exactly how I had envisioned it, my left arm's a bit sore today.
The yarn is Blue Sky Alpacas Cotton - this particular one isn't one of the dyed cottons, however, so it's 100% organic. There's some shedding, but not a substantial amount. It's actually very soft -- and that makes up for any difficulties I had with it. One skein yielded about 54". While it's not as long as other scarves I own, by the time I crocheted the last motif, I was ready to be done anyway. In that respect, it's just the right length.
When I was reading Kim's Ravelry page for her scarf, I noticed that she used a free pattern. The patterns we each used are very similar, but the MK Caroll version I purchased has excellent diagrams in the format I like the best -- the diagram is next to the written instructions. That way, if I don't understand the written instructions, I can refer to the diagram to check myself:
If you're inspired to make one of your own, consider this a nudge -- it's easier than it looks!
