I’ve got this laceweight mohair from http://www.thenaturaldyestudio.com/ and its absolutely gorgeous. The pattern calls for Rohan Kidsilk Haze, which I know is lovely but it really is quite pricey.
One of the skeins (I have three!) was wound into a ball by friends when I took it to the knitting group, its 400 yards per skein so I can’t imagine I’m going to manage to crochet all that while I’m away.
The pattern is “Beaded Cobweb Wrap” from Erica Knight’s Essential Crochet, uses a 6mm hook so the pattern is more space than yarn anyway, and it looks quite easy once you’ve done the cast on – its crocheted longways, so there’s a mad long chain that you have to hook into to start with, something I always struggle with. I’ve been assured it’ll look like chewed string until I block it and that I should just carry on regardless – I’ll let you know how I get on :)
