Julie, Thanks for posting an image of the yarn. Lovely colours! I've used a Filatura di Crosa yarn Zara which is pure merino but has the same look. That way the ply twists 'across' seems to make for a comfortable garment and a nice soft look. I was interested to hear the cotton/acrylic blend worked so well and wasn't hot. :-)
Nobones, sorry to hear also and great though you can give advice as to what works and what may not. So, some of the aviator style hats etc - for autumn/winter especially - would be really welcome I imagine. I've always liked your avatar. I imagine a kitty claw grabbing a finger any moment!
