Members of a knitting group I meet with have crocheted a simple, triangular shawl - really half a granny square - out of Seasilk. It's very effective and they all seem to have enjoyed doing it. I haven't got any Seasilk, but I have got some Alchemy bamboo yarn in a blinding red and shocking pink colourway and I thought it might work. I bought it at the first Ally Pally show I went to, in about 2002.* Anyway, I dug the yarn out of my deepest stratum of stash last night. I bought it as a kit to make a market bag, so it came in rather a posh tote bag and there's a pattern enclosed. There's also a receipt. I cannot believe how much I paid for 100g. Are sitting down? £66!
All I can think is that I was so overcome by my first experience of a knitting show that I just lost all sense of proportion. Also, I have to remember that there was nothing much available then even online. In a sense I was an 'early adopter'. As with televisions and computers, if you wait long enough prices come down eventually. I can't find the bamboo yarn at a UK shop but it's $28 per 50g at Purl Soho.
*I can't remember exactly, and the receipt is not dated.
