Take 2 and I finally got the sizing right. It fits perfectly and I'm happy.
I made the small with no pattern adjustments. The yarn is Tahki Cotton Classic in sand, but it looks more like blush to me. I only used 4 skeins, 2 less than the pattern requirements. I'll just have to exchange my extra yarn for something else. Hmmm, maybe some Debbie Bliss Cathay for Picovoli. Thank you for your good gauge vibes and encouragement.
